The Great Muppet Caper/Funny

• The entire dang movie, really, but here are some specific examples:
• "You can't even sing! Your voice was dubbed!"
• The goldfish randomly appearing in Miss Piggy's fantasy sequence.
• Gonzo hailing a cab. By throwing himself down into the middle of the street.

Yeah, it's great when it works!

• The scene where both sides (Nicky and his cohorts, the Muppets) are checking their equipment before moving out. While Nicky's gang have the usual stuff, the Muppets' list is a bit...strange.

Fozzie: Wax lips.
Zoot: ...Man, I just had 'em!
Dr. Teeth: Did you leave 'em in your other pants?
Zoot: I ain't got no other pants!

• The whole "17 Highbrow Street" scene, from the fact that the address actually exists to John Cleese's completely non-chalant reaction to finding Kermit and Piggy in a closet and recommending a restaurant to them. Although it's really more of a supper club.
• Gonzo attempting to pay for dinner... by selling pictures of the diners for ten dollars a pop. Keep in mind that the dinner was in the thousands of dollars. And one of the couples was a cheating husband and his mistress.

Man: No, no pictures.
Gonzo: Aw, but it would be a great momento for you and your wife.
Man: My wife isn't feeling well.
Gonzo: That's too bad, maybe she should be at home.
Man: My wife is at home!
Gonzo: (Stammers incoherently) Yes, next table!

• Fozzie starting a chain of blabbing about Kermit's date, and then inviting everyone at the hotel to go along with him.
• The entire first ten minutes, which take a complete and total wrecking ball to the fourth wall by starting with the Muppets lampooning the opening credits and follows it up with a musical number called "Hey, a Movie!".
• After the Happiness Hotel song, Sam the Eagle peeks out of his room to say: "You are all. Weirdos!"
• Kermit taking one look at the supper club's menu and just about having a heart attack.

Kermit: It's just sort of amusing that the roast beef is the same price as an Oldsmobile.

• This exchange between Lady Holiday and Nicky:

Lady Holiday: I feel as if thieves are breathing down my neck.
Nicky [while breathing down her neck]: Thieves aren't breathing down your neck!

• Kermit and Miss Piggy having an in-character argument about why Piggy lied about being Lady Holiday, which devolves into an out-of-character argument about Piggy's overacting. It really has to be seen to be believed.
• Kermit, Fozzie and Gonzo arriving in England by being shipped ninth-class (in boxes that resemble jail cells) and then thrown out the plane into a pond. (Gonzo, of course, loves it.)

Steward: No, the plane lands in Italy! You land in England!

• Kermit proposes a counter-offensive to prevent Nicky's gang from stealing the Baseball Diamond. He emphasizes the danger, and says, "if anyone wants out, now's the time to say so." (Is there a trope for that?) Immediately, everybody except Gonzo and Fozzie starts opting out!
• The entire scene where the Muppets and villains begin to play an impromptu Baseball game with the Baseball diamond, complete with Louis Kazager doing commentary!
