An insane asylum. He hears voices on the inside chanting "thirteen,thirteen, thirteen".
He is curious why they are chanting that. He looks around and finds a hole that allows himself to look inside the fence. As he puts his eye on the hole a stick jabs him in the eye. And the chant changes to "fourteen, fourteen, fourteen".
My dad tells this joke all the time.
