Leper Hockey

Alright listen up, buttercup. This joke is about lepers, which are people with a gross disease that makes their skin fall off. The punchline is a play on words: a "face-off" in hockey is when two players stand face to face to start the game, but for a leper, it means their face falls off. It's funny because it's icky and plays on the disease. You probably need a lot of help, dummy.
