Thirteen!
　　A guy is walking past a big wooden fence at the insane asylum 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!"十三
