Topic on Forum:Trope Talk

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.
