A guy is walking past a big wooden fence at the insane asylum（精神病院） and he hears all the residents inside chanting: " Thirteen! Thirteen! Thirteen!" Quite curious about this, he finds a hole in the fence and looks in. Someone inside pokes him in the eye. Then everyone inside the asylum starts chanting, Fourteen! Fourteen! Fourteen!
