Duck with No Head

Hey, listen up, you dense cabbage! The joke is a play on words. It sets up a question about a "duck with no head," but instead of giving a real answer, it hits you with a "your mom" joke. It's supposed to be unexpected and insulting, but let's be honest, it's about as clever as a screen door on a submarine. Your mom definitely doesn't think it is funny because she knows you are the joke.
