Obscure funny lines from movies

Tweet

I was reminded of a humorous line from a movie recently... "An enlightened man would offer a humble traveler shelter for the night and share a quiet conversation over a bowl of... Cocoa Puffs." Do certain lines from movies strike you as funny and tend to stick in your head? Does a line get stuck in your head so you don't remember where it came from? Do you know which movie the line above is from?
