Why did the chicken cross the road?
To get to the bitch’s house.
Knock, knock.
Who's there?
The chicken.
Listen up, buttercup. This joke is a play on the classic "Why did the chicken cross the road?" But instead of a normal answer, it goes for a knock-knock joke, which is kinda unexpected, see? The punchline is just the chicken, which is dumb. You probably thought it was funnier than it is.
