Ironic Juxtaposition

A kind of visual technique, usually played for laughs. It features an inanimate object, such as a sign or billboard, and something in or of the real world. While the sign is making one very clear statement, the real thing will be portraying a reality that is completely different in nature. The sign, as a result, will appear to be either surreal or completely ineffective considering its general surroundings.

A subtrope of Mood Dissonance. When played for drama, is usually extremely bleak and depressing, and a sign of a Crapsack World.

Examples of Ironic Juxtaposition include:

Film

• Jurassic Park: "Objects in the mirror may be closer than they appear."
• One of the Lethal Weapon movies features a cool rebellious lead character standing in front of a non-smoking sign and smoking. You know, 'cause he's cool.

Live-Action TV

• There's a really dark example in Threads, where shell-shocked nuclear survivors are seen shambling past posters of happy, smiling babies.

Literature

• In Moonraker (the book), James Bond sees a billboard. The sign reads in blinking neon, "SUMMER SHELL IS HERE" but due to the angle at which he sees it, it says "HELL IS HERE...HELL IS HERE...HELL IS HERE".

Music

• The music video of the iconic Dutch song 'Vijftien miljoen mensen' features a photo of a 'do not walk on the grass' sign, with a policeman cheerfully chatting with someone on the wrong side of it while dozens of people lounge about the grass.

Web Comics

• In Dead Winter, Lou's van nearly squashes a soldier (who had tried to blast it with a RPG) against a wall. Right under a billboard:

"That was a close shave!"

• From The Perry Bible Fellowship: Post Apocalyptic.

Web Original

• This happens all the time with Internet ads, mostly because of their context sensitivity. There are screenshots of things like a news story about an infant dying in a house fire with an ad next to it for a CD burner saying "burn baby burn." There's also Ad Placement Fail on Failblog.
  • Invoked in a Cracked.com Photoplasty contest.
  • Worst one of those I've seen, though, was while watching a clip from Blood Diamond - the "sponsored video" on YouTube was for a diamond company's ad. I wish I were making that up.

Western Animation

• Ín Danny Phantom, the "Welcome to Amity Park" sign changes regularly, and sometimes does this, such as "Amity Park ? it's safe here!" right in front of a ruined town in the midst of a ghost attack.
• In The Venture Bros., there's a jolly sign with a smiling family stating, "If you lived here, you'd be home right now," Just outside the desolate trailer park that Pete White and Billy Quizboy inhabit. They are the trailer park's only residents.

Real Life

• Perhaps the most famous examples of this are the Depression era photographs by Dorothea Lange, which contrasted extremely cheerful billboard advertisements with happy American families with the desolate ghost town that most of America had become. The worst of it is that these advertisements stayed up during most of the Depression- largely because no one could afford to take them down and put up new ones.
