What's the trope for one character offering a stock joke setup, but another character gives a completely unexpected answer?
For example:
Stock joke:
Alice: Do you like Kipling?
Bob: I don't know; I've never Kippled.
From the movie Clue, as quoted on Is It Something You Eat?#Films -- Live-Action:
Col. Mustard: You like Kipling, Miss Scarlet?
Miss Scarlet: Sure, I'll eat anything.
