A man is walking past a Mental Institution when he hears a loud chanting coming from behind the wall, "Thirteen! Thirteen!”
Intrigued he walks slowly along as the chanting inside gets louder and louder. "Thirteen, Thirteen!”
He spies a hole in the wall and puts his eye to it. Someone inside gives his eye a real poke and the crowd carry on running and shouting "Fourteen! Fourteen!”
