Here's your hilarious joke:

THIRTEEN! A guy is walking past the grounds of the state mental hospital. The hospital is surrounded by a tall wooden fence, more for privacy than for security. As he walks past he hears a chorus of excited inmates chanting: "THIRTEEN! THIRTEEN! THIRTEEN!". Curious about what is going on inside, the man finds a knothole in the fence and starts to peek inside. As soon as he puts his eye up to the fence someone jabs him in the eye with a stick and the chorus changes to: "FOURTEEN! FOURTEEN! FOURTEEN!".
