Homer: All right, Marge, I'll tell you, but first you have to promise you will not get mad.
I promise I will
get mad, because I always do when you make me promise I won't.
Two characters have a conversation like this:
Character A: I need some advice from you.
Character B: Shoot.
Character A: Promise me you won't laugh, okay?
Character B: Okay then.
Character A: How do I get rid of this rash in the shape of lovehearts on my left buttock?
Character B: Bwahahahaaha!
Character A: You promised you wouldn't laugh!
Character B: Sorry dude, I didn't mean to.
Sometimes Character B is Character A's friend; they may try to unsuccessfully stifle the laugh. If they're The Rival
(or The Jerkass
) then they'll probably just be in peals of laughter. "Promise me you won't laugh" isn't the only scenario, though; sometimes it's substituted with "you won't scream", "you won't panic", "you won't get mad" or something similar. Almost every time the person goes back on the promise. Beginning to be subverted more and more often in the style of The Simpsons
quote at the top of the page, or by someone saying "I'm not promising anything till I hear what you say."
Another variation on the trope is a conversation that goes something like this:
Character A: What happened?
Character A: No really, tell me.
Character B: *insert gross/inappropriate/silly/ridiculous story here*
Character A: ... you were right. I didn't want to know.
