Charlie Brown Knock-Knock

Alright, listen up, chucklehead. This is a knock-knock joke. Someone says "Knock, knock," and you, being the dummy, ask, "Who's there?" Then the first person gives a name, Charlie, in this case. You then ask, "Charlie who?" And here's the kicker: the response is "Charlie Brown! Good grief!" Get it? It's a play on words! Wow, I'm surprised you could even read this far, you smooth-brain.
