As of January 2013, it had the largest market share for its timeslot; with between 13 and 17 percent of Korean television viewers watching Infinite Challenge every Saturday night.[3] making it the most-watched free-to-air television program on Saturday evenings, and the most viewed non-drama program in South Korea every week (excluding special sporting events, since November 2006, with the exception of January 2009,[4] April and May 2010[5]).[6]

Infinite Challenge has kept the same scheduled time, since first airing in 2005. Since 2009, it lasts for roughly 75 minutes, excluding ten minutes of advertising. Episodes are also frequently rerun on several Korean cable broadcasting channels.[7] Since February 19, 2011 (episode 237), the program has been aired in high-definition.[8] Infinite Challenge has been called "the nation's variety show" and "Korea's real first variety" for having been successful for over ten years.[9]

In March 2018, it has been announced that, following the departure of lead producer Kim Tae-ho,[10] all current members have stepped down from the show,[11] bringing the program to an end. The last episode was aired on March 31, 2018, but the program has continued for 3 more weeks with recap special that looks back at the program over the years.[12][13]

Contents

Infinite Challenge is recognized as the first "Real-Variety" show in Korean television history. The program is largely unscripted, filmed in almost-secrecy and followed a similar format of challenge-based reality television programs. The challenges are often absurd or impossible to achieve, so the program takes on the satirical comedy aspect of a variety show rather than a standard reality or competition program. In earlier episodes, the show's six hosts and staff would continuously proclaim that, in order to achieve its comedic purposes, the program had to be "3-D": Dirty, Dangerous, and Difficult.[14] It gives people fun to try things that seem impossible.

Recurring segments

These segments were featured in multiple episodes over the years due to their popularity.

• "Infinite News" – a parody on news broadcast in which most of the reported stories happened to some or all of the cast members. Those stories revolve around their personal life and tend to balance between facts and the comedic side of them.
• "Infinite Company" – an unscripted skit that parodied on the lives of office employees, similar to The Office. Initially, the skit was a reproduction of the late comedian Kim Hyung-gon work, called President, President, Our President, portraying a situational comedy around a board of directors of a company before it was changed to be about a group of employees in a small department.
• "Ha & Su" – an unscripted situational comedy around the petty quarrels between Jeong Jun-ha and Park Myeong-su, where the latter is aggressive and hot-tempered while the former is timid and simple-minded. In 2011, they were awarded a "Best Couple" award for their performance.[15]
• "Jimotmi" – it stands for 지켜주지 못해서 미안해 (jikyeojuji motaeseo mianhae), which means "Sorry I could not look out for you" In this segment, the members play hidden-camera pranks on each other to see how they react to certain contrived situations.
• "Introducing My Ugly Friends Festival" – A segment where the members invited their acquaintances which they considered visually unappealing. Afterwards, the members organize a party where they celebrate with various games.
• "Saturday, Saturday's, I Am A Singer" – Suggested by Park Myeoung-Su and Jeong Jun-ha where the program arranges a stage where old artists were given chances to return and perform their hit songs. Sechs Kies and H.O.T. were able to reunite and came out of retirement through this segment.
• "Please, be..." – a segment which was introduced to instill common principles to all of the members. '"Please, come early"' forces the members to be punctual during filming day as the staff will not inform them when they would filmed the segment. '"Please, be friendly"', featuring Haha and Jeong Hyeong-don, were created to encourage both members to be more comfortable around each other.
• "Ah-Ha" – a Korean word game in which one member says a word, and the next person must then say that word backwards. Members who failed or made mistakes would be hit over the head. This segment premiered in the 2nd season (Infinite Challenge – The Master of Quiz) and was played occasionally in following seasons.
• "One-flash Telepathy" – after hearing a word which was given from the production booth, each member presented a gesture that would best represent that word. A round is cleared if all six members perform the same gesture and punishments were given when they failed. The original alleged purpose of this segment was to unite the minds of the members; however, they have yet to succeed. Voice narration for this segment was provided by Na Gyeong-eun, an announcer and Yoo Jae-suk's wife.
• Television Advertisements – throughout the episodes, the hosts create some satirical Korean television advertisements.
• Calendar-making Project – the members created a series of unique calendars and donated all profits from these sales to charity. This project has succeeded every seasons.[16]

National events

Some of the segments of Infinite Challenge also grew and become a national event where it also actively involved the audiences as well.

• 2008 Host-in-Chief Elections – after a humorous request by Park Myeong-su to have a new leader in 2008, all Infinite Challenge members and staff held a vote for a new 'host-in-chief' on December 31, 2007, at the nation's own natural gas field near Ulsan.[17] Prior to the election, each member created campaign pledges to encourage voters to vote for them. All entertainment managers, coordinators, MBC staff and the members voted at the South gate of the MBC Headquarters and the votes were counted on the morning of New Year's Day. Afterwards, Park Myeong-su was declared the new host-in-chief, but evidence showed him of tempering the voting box. The new host-in-chief was given 3 weeks to prove his leadership skills. However, after poor performances for 3 whole weeks, Park Myeong-su announced at an Infinite Challenge press conference that he would step down and wait for the new election to take place. In the aftermath, Yoo Jae-suk was appointed as interim host-in-chief on February 2, 2008. The second host-in-chief election was held on February 4, 2008 at the MBC Dream Center in Ilsan and Yoo Jae-suk won the majority of the votes and was once again reinstated as the host-in-chief.
• WM7 – the "Wrestling Muhan 7" project is an attempt by the members to perform at a professional wrestling event. From July 2009, the members started training by inviting Sonstar, junior-professional wrestler and the drummer of Cherry Filter, as their coach and Park Myeong-su as their club leader. After numerous injuries, including a concussion suffered by Jeong Hyeong-don, setbacks and delays, the members finally put on a performance in front of a live audience on August 19, 2010 at Jangchung Gymnasium. It was broadcast over 11 episodes and MBC also released a DVD edition of this challenge, featuring several unaired segments, stories and the full uncut performance.
• 2014 Decision – the show held another host-in-chief election in 2014 where the show elected a host-in-chief with 10 years tenure. A nationwide election was held, which also promoted the citizen's participation on South Korea's 2014 local elections.[18] Similarly, the members created campaign pledges to attract viewers to vote for them in the preliminary internet polls. The second internet poll was held after the special's first episode was aired. In the aftermath of the second poll, Haha and Jeong Jun-ha decided to support Jeong Hyeong-don while Park Myeong-su forfeited to support Yoo Jae-suk. About 50,000 people, including the members of Infinite Challenge, cast their votes on May 22, 2014 on the polling stations at ten major cities on South Korea (Seoul, Incheon, Daejeon, Daegu, Ulsan, Gwangju, Busan, Jeju, Chuncheon, and Jeonju). Another 34,000 people cast their votes earlier on the preliminary voting on May 17–18, 2014. Internet voting also held at the same time of actual poll for the people who were not able to cast their votes on the polling stations and 363,047 people participated on it. Combining the live polls and the internet votes, Yoo Jae-suk won the election by defeating Noh Hong-chul with 45,310 marginal votes or 8.29% of the combined votes.
• Infinite Challenge Song Festival – started in 2007, the members randomly collaborate with real musicians in order to compete for the "Infinite Challenge Song Festival" that is held every two years. The first festival was won by Haha with "The Story of a Short Kid" (키작은 꼬마 이야기).

History

• "Infinite Challenge," which aired its first broadcast on May 6, 2006, is Korea's first real variety program. With the success of the program, other broadcasters have also produced real variety programs. The advantage of Real Variety was to ensure that even a popular celebrity who had been recognized as a special person was no different from an ordinary person.[19]

Season 1

Further information: List of Infinite Challenge episodes § Season 1

The title of Season 1 was Rash Challenge (무모한 도전). Led by Yoo Jae-suk, six or more Korean entertainers (with Noh Hong-chul and Jeong Hyeong-don as a regular members) tried to complete a 'sporting' mission in an outdoor studio, which was based on a viewer's suggestion submitted through the show's homepage. Some of the absurd challenges included racing in a foot-powered swan-shaped paddle boat against a motor boat, playing a tennis match against Maria Sharapova, appearing live on stage at a public fashion show, and playing football against Thierry Henry. A large part of the humor comes from the fact that the cast is generally not well-suited to the challenges they attempt. This program can be compared to the filmed-in-studio Wetten, dass..? of Germany, as the program mainly focuses on the process and progress of the challenges, rather than focusing on the accomplishment of a mission.[20] This format lasted only from April 23, 2005 to October 22, 2005. Despite having a strong following, its average ratings were very low (roughly 5 percent). Due to its sports-related theme, reruns of Season 1 and sports-related episodes of Season 4 (i.e. WM7) episodes are frequently aired on MBC Sportsplus, MBC's satellite and cable network for sports-casting.

Season 2 and 3

Further information: List of Infinite Challenge episodes § Season 2 and 3

From October 29, 2005 to April 30, 2006, Season 2 was titled Excessive Challenge (무리한 도전). For the first few episodes, the program was fairly similar to the first season. However, because the cast members wanted to redefine their characters, they decided to change the whole program concept, calling it Infinite Challenge - Master of Quiz in the third season. Since then, six hosts (with Yoo Jae-suk as 'host-in-chief') played a Korean-letter game called 'Ah-ha' (see below); competed in their knowledge and mental power; participated in on-line popularity polls about specific themes; and explored other comic features.[21] Although the average ratings were low, the unity and dynamics of the members significantly improved. A panelist from Season 1, Park Myeong-su, came back as a co-host, and Haha and Jeong Jun-ha also became co-hosts of the program.

Season 4

Further information: List of Infinite Challenge episodes § Season 4

On May 6, 2006, the fourth and final season (format) of the program that now simply known as Infinite Challenge (무한도전), went on air. Special coverage of 2006 World Cup Germany was featured for the entire month of June 2006, along with some 'Ah-ha' specials (with Shinhwa, for example) at the beginning of each episode. However, in July 8, 2006, the program took its memorable first step as the first 'Real-Variety' television program in Korean television history, with the airing of a segment called 'Please, come early': The six members were asked to come to the recording session on time or experience some form of punishment (일찍 와주길 바래, a part of the 'Please, be...' series see below), combining elements of both Reality TV and Variety programming, including comic characters from each of the Infinite Challenge members, see 'hosts'). Thereafter, the program has created challenges with regard to anything related to real life (excluding some critical issues such as religions and sexual preferences), in outdoor studios, with little use of acting or heavily based plotting. Since December 2, 2006, the program has received the highest ratings of prime-time lineups for Saturday evening.[22]

In January 2012, the program took a 6-month hiatus due to a labor strike conducted by MBC's reporters and producers. During this period, new episodes were not produced and MBC, instead, aired reruns of previous episodes.[23] In November 2015, Infinite Challenge arranged special exhibition and expo titled "Infinite Challenge Expo", in KINTEX.[24] The program took a 7-week hiatus from broadcast in early 2017, which Kim Tae-ho, the main PD, signified as a period to normalize the production process which has been shortened considerably where the production team had less time and always rushed to meet the deadline. The PD also reveals that the program still continues their regular shooting schedules while being off the air.[25]

The program took another 10-week hiatus from September 9, 2017, due to a labor strike by MBC's reporters and producers. During the strike, new episodes were not aired and reruns of previous episodes were broadcast.[26] The strike ended on November 13, and Infinite Challenge returned to regular broadcasting on November 25.[27][28][29] In March 2018, the program came to an end marked by the departure of Kim Tae-ho, the lead producer, which was followed by the members. However, after the last episode was aired, the program returned for 3 more weeks where it aired recap specials that pays tribute to the achievements of the program called "13 Years of Saturdays".[10][11][12][13]

This is especially prevalent when Myeong-su's receding hair is flattened or his make-up is removed. See his page for more details. His (on-air) persona is that of a veteran grumpy "upperclassman" of the other members. He often shouts or reprimands his "underclassmen," usually about humorously trivial matters. Thanks to his current work as the co-host of Infinite Challenge, Park Myeong-su gained more than 250 nicknames throughout his appearances on the program as listed by the netizens.[33]
Jeong Jun-ha (정준하)	March 2006 - March 2018	The Helmet (헬멧),[34] The Lord of Eating (식신) Monster (괴물) The Third-in-command (3인자) Stupid brother (바보형) Mr. Jeong Joong-ang (정중앙씨) Fat-fatso (뚱뚱보) Jjeori Jjang (쩌리짱) Global Moron[35] Cool Guy(쿨가이) Manager Jeong (정총무) Jeong Jun-yeon-a(정준연아) (Kim Yuna Parody) Somewhat lacking but a good friend (약간 모자라지만 착한 친구) Jonathan(조나단) The Lovester(사랑 전도사, 사랑꾼) Wax drippings Jeong (정촛농) Grandfather (할아버지) Icon of Aging (노화의 아이콘) Variety Show Zombie Jung Jun Grandfather (정준 할아버지) The man that shook the world through dieting Funeral Photo Jun Ha (영정 준하) The Creation Myth of The Dieting World (다이어트계의 신화창조) Ndotto's Father (도토 아빠) MC Minzy (MC 민지)	His character is mainly defined by 3 things: his size (often referred to as being 0.1 tons, or 100 kilograms), appetite, and a degree of slowness in judgment. His extraordinarily large head (supposedly 8 kg) has gotten him, on a few occasions, called "Chivas Degal" (Degal = is a shortened word for "Degari", a vernacular word for "head"). In the 50th episode special of season 3, he was challenged to eat 50 plates of noodles in five minutes. The plates altogether weighed about 10–30 kg. (He succeeded, but had to go straight to the lavatory and subsequently slept in the back of the studio). On episode 61 of season 3, he went to a hair salon with Hong-chul to curl Hong-chul's hair. He asked a woman who was working there if she knew Jun-ha's name, but she said Joong-ang by mistake. Since that time, the members, including the creator Yoo Jae-suk, have frequently teased him as Mr. Jeong Joong-ang (정중앙씨), which means 'Mr. Square-in-the-middle'.
Haha (하하) (Ha Dong-hoon, 하동훈)	December 2005 - March 2008 March 2010 - March 2018	Shorty (단신) Childhood friend(with Noh Hong-chul) (죽마고우) Little one (꼬마) The M.A. Ha (석사 하하) The Top Little one(상꼬맹이) The Friend Who Lacking If Compared With the One At the Same Age (또래에 비해 떨어지는 친구) Hybrid Sammy Sosa Rio Levy (하이브리드 샘이솟아 리오레이비)	Haha is long considered the cutest and best-looking member of the cast. He is also the most-educated member, having obtained a Master of Arts in Theatre & Film at Daejin University; however, during the episode of the 50th special, he only got 20 points on a 100-point elementary-level spelling test. In episode 62 of season 3, he sang a song called 'A Little Boy's Story' (키작은 꼬마 이야기) as a tribute to his short height, which is a constant target of ridicule among the cast. It was a huge sensation with viewers. Haha temporarily left the show from March 2008 through March 2010 in order to fulfill his mandatory military service. In his final episode before entering the service, Haha performed at a guerrilla concert that was secretly organized by his fellow co-hosts.
Hwang Kwanghee (황광희)	April 2015 - March 2017	Kwanghee	Hwang Kwanghee was the youngest member among the cast of Infinite Challenge while he was on the show. A member of ZE:A idol group, Hwang Kwanghee joined the Infinite Challenge cast in April 2015. He was selected through the Sixth Man project which was held in order to fill the empty position after Noh Hong-chul left the program following a drunk driving incident. Kwanghee left the program in March 2017 in order to fulfill his military duty.[36]
Jun Jin (전진) (Park Chung-Jae, 박충재)	July 2008 - November 2009	Junstin Jinberlake (전스틴) The roll-in kid (굴러들어온 놈) Jan Jin (잔진) The Million Dollar Boy (백만돌이)	In June 2008, Shinhwa member Jun Jin appeared on the show to replace Haha. Jin showed his extraordinary physical talent and was a target for all the other members of Infinite Challenge, who envied his looks and abilities during many challenges.
Gil (길) (Gil Seong-joon, 길성준)	April 2009 - April 2014	Baldy/Bbaak-Bbaak-ei (빡빡이) Come between-Gil(이간길) Honey jar(꿀단지) Fat-fat-fatso (뚱뚱뚱보) Ip-sae (입새) (as he only brushes his teeth once a day) Gilmeo (길메오) (as a 'cameo' proclaimed by Yoo Jae-suk) Overreacting (무리수) The friend who born unfunny (태생적으로 재미없는 친구) Icon of Betrayal (배신의 아이콘)	Gil made his first appearance on an episode which featured Korean figure skater Kim Yuna in April 2009, ostensibly substituting for Jeong Jun-ha, who had to leave the episode recording early. He remained a de facto member of Infinite Challenge until he became a full member later that year. During the Boxing episodes in January 2010, Gil showed off his 9-year-long training in the sport. Gil is often called the Unfunny Friend due to his inability to ad-lib as quickly as the other co-hosts. On April 23, 2014, Gil was caught by the police due to drunk-driving. Fans of the variety show have been flooding the board with requests for Gil to leave the show for his inappropriate actions. Eventually, the MBC executives announced his leave on the same day.[37]
Noh Hong-chul (노홍철)	April 2005 - November 2014	Stone Kid/Psychopath/Crazykid/Dol+I ('돌+아이'),[38] Childhood friend(with Haha) (죽마고우) Quickmouth (퀵마우스)[39] Noh Jji-rong (노찌롱) Global Fraudster(글로벌 사기꾼) Noh big-jaw(노하관) Fraudster (사기꾼) Affirmation Noh (노긍정) Anal Fistula Patient(치루치루) Dekopon (한라봉) Ppakku (빡구)	'돌+아이/Dol+I' was created by Yoo Jae-suk during episode 22 of season 3. Quickmouth was his original character, due to his ability to speak very rapidly. 돌+아이 (when written without the plus sign) is a Korean curse word meaning psychopath, or an extremely crazy person. Since this is a show watched by families, the staff humorously put a plus (+) sign in the middle to separate the word so its literal meaning becomes 'Stone+Kid' when in actuality it means 'psycho'. On-screen graphics often depict this nickname by displaying a large capital 'I' that looks to be made of stone ('아이' is pronounced like the letter 'I'). Similarly to former member Gil, Noh Hong-chul was caught driving under influence of alcohol on November 7, 2014. Following the incident, Noh Hong-chul released an official apology to the public through MBC.[40] On the afternoon of November 8, MBC announced that Noh Hong-chul would be leaving the show and Infinite Challenge would continue on with the five remaining cast members.[41]
Jeong Hyeong-don (정형돈)	April 2005 - November 2015	Fatso (뚱보) Awkward fatso (어색한 뚱보)[42] Jinsang (진상, nuisance) Jeong Hang-don (정항돈) The Moon (달님) Doni (도니) Crazy Existence (미친존재감) Gaehwadong Orange-Tribe (개화동 오렌지족) Top Four MC (4대천왕)	A comedian by profession before joining the team, Jeong Hyeong-don used to appear in the Korean comedy show Gag Concert (where Do-Re-Mi Trio being one of his many skits). However, over many episodes, he has demonstrated remarkable talent in everything imaginable (for example, catching grapes with his mouth or playing a Korean jump-rope game) except being funny. He is teased by the other members for this. His character is also defined by the ability to make anyone around him feel awkward (as seen in the earlier episode) In November 2015, Jung Hyeong-don had suspended all broadcasting activities due to health reasons. On July 29, 2016, Jeong Hyeong-don's label, FNC Entertainment, officially announced that Jeong Hyeong-don would permanently leave the show after a nine-month hiatus from the broadcast due to poor health condition.[43][44]

Whenever he was given a chance to appear on-screen, he was often ridiculed by other cast members for attempting to constantly outperform others and for overacting in order to gain attention.

Choi (Man-neung Choi-codi /만능 최코디)	Entertainment Manager of Jeong Jun-ha	As Jeong Jun-ha's coordinator, Choi also hoped to become a rising star as a professional actor his common hope of rising stardom (as a professional actor), with a lot of help from Jeong Jun-ha himself.[45] He prepared a bunch of radishes for the members on 'Kimchi Preparation' (S03E30) and 'Jun(Semi-) Hines Ward'(S03E77) episodes well, and he presented his professional agricultural skills on the episodes 'MD Goes to country' (S03E25) and 'Rice-planting' (S03E56).

She appeared for the first time in episode 83 of the third season; her closing comment of 'Hit that jackpot!' (Dae-bak Teo-ji-se-yo! 대박 터지세요) became an enormously popular new-year greeting.
TEO Kim Tae-ho (김태호)	Bro. TEO (태호 형) TEO PD (태호 PD)	Executive Producer of Infinite Challenge	A pioneer of Korean entertainment, Kim Tae-ho produces and directs the show. Besides helping to create the unique Real-Variety format, Kim also innovated Korean television by adding unique captions to the show. Although captions are commonplace on Korean variety shows, Kim's captions went beyond simple descriptions or commentary, adding information on cast members' emotions and expressing reactions to the show, giving the captions an interactive feel that aligned with the viewing audience's thoughts. With high sensitivity for fashion, he gained extraordinary popularity when he officially opened his 'Cyworld' webpage. Although his presence is mostly felt through his captioning and occasional off-screen soundbites, he appeared as a witness of the Moot court challenge, which aired on February 20, 2010.
Kim Tae-hee (김태희)	Writer Kim (김태희 작가)	Writer of Infinite Challenge	As a high-profiled co-writer of Infinite Challenge and a Korean actress-namesake, she enjoys her huge popularity from dedicated viewers.

Shin Mi-so (신미소)	Miso Co-ordi. (미소코디)	Fashion Co-ordinator of Yoo Jae-suk	A Busan-native who helped assemble Yoo Jae-suk's wardrobe, Shin was also a popular 'guest' on the show. She debuted during a '100-minute Debate' (episode 42 of season 3), in which she was caught falling asleep in the audience. This incident made her name the top online keyword of March 2007. She was also featured when she accidentally broke a set of illuminators when Lee Young-ae appeared on Infinite Challenge (episode 52 of season 3). She eventually appeared as a co-host of 'Madness Couples' (episode 75 of season 3) with the Host-in-chief Yoo Jae-suk. She was known to be able to argue with all six members of the show, earning her the nickname 'Aegis ship.'

• During the 12th episode (aired on August 16, 2007) of MBC's Monday-night variety programme 'Jippijiggi'(지피지기), comedian Park Su-hong urged Noh Hong-chul, Jeong Hyeong-don, and Ha Ha (members of Infinite Challenge) to create a new comic-variety program called 'Yuhan Dojeon'(유한도전, 有限挑戰, Finite Challenge). However, this was a joke when he attended this program as a guest.[58]
• MBC Drama, MBC's Drama and Entertainment channel on Skylife and Cable TV, has decided to launch a brand-new comic variety show called Infinite Girls (무한걸스), the female edition of Infinite Challenge. Six Korean entertainers including Song Eun-i, Shin Bong-sun, Kim Shin-young, Hwangbo, Baek Bo-ram and Jung Ga-eun serve as the co-hosts of this program. Previous hosts who have already left the show include Ahn Hye-kyung (안혜경, who is former Haha's girlfriend), Kim Hyun-sook (김현숙), Bin-woo (빈우), Kim Ga-yeon and Jung Shi-ah.[59] It aired on September 23, 2007, as a pilot (special) program for Hangawi holidays. Since October 15, 2007, This format went a regular-scheduled programme at the MBC Every1, MBC's Cable and Satellite network for comedy and variety shows, eventually.
• On December 27, 2007, the SERI, a well-known economic research institute of South Korea, picked this program as the 6th most-influential product and service of the year 2007, due to its strong public popularity and its own productive characters.[60]
• Infinite Challenge is often mentioned on other similar programs, when guests asking if the staff of the show in question copied the idea for a segment from Infinite Challenge.
• In the first quarter of 2008, the Global Marketing Department of MBC reported that MBC had attempted to sell the format of Infinite Challenge to a European agency in Sweden. This was the first time in Korean television history that such a deal had been made. However, the contract was not finalized, as there were too many characters on the program for the Swedish company to reproduce. Even so, rights to the show were eventually sold to Air France and Qatar Airways' in-flight broadcast.[61]
• The creators of Infinite Challenge filmed an advertisement about Bibimbap which has been shown in Times Square since November 26, 2010.[62] Due to this involvement, the Ministry for Food, Agriculture, Forestry and Fisheries had been put up a Plaque of Honour, to acknowledge MuDo's dedication.[63]
• In 2011, Infinite Challenge held the West Coast Highway Music Festival. At this festival 7 teams participated and everyone got a trophy.[64]
• The show is also famous for its loyal fans, especially from the youth demographic. Despite the show’s hiatus of 22 weeks due to MBC’s Union Labor Strike in 2012, the show was able to keep its strong popularity with television audiences. It was acclaimed as "the most favorite program in South Korea" numerous times.[65][66]
• Members of Infinite Challenge cast (Yoo Jae-suk, Park Myeong-su, Jeong Jun-ha, Jeong Hyeong-don, Noh Hong-chul, Haha, Gil) are featured on "Gentleman" music video by Psy.[67]

Plagiarism

It has been alleged that the show was copied without permission by a Chinese variety program called Go Fighting.[71]

According to production company MBC: "Currently in China, multiple broadcasting and production companies are saying they are personally producing 'Infinite Challenge' or a similar program, causing a disturbance in the market and damaging MBC Contents' image. From hereon, excepting the broadcasting of 'Infinite Challenge' on CCTV1, we will take firm legal action against any behavior that has nothing to do with MBC while making people confused and misunderstand [that program] as MBC's 'Infinite Challenge."[72]
