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!

一个人在精神病院的木围墙外路过,听见里面所有的人在唱,十三!十三! 十三!

他很好奇,就找到围墙的一个洞,然后看进去。突然有个人捅到了他的眼睛。

然后里面所有人开始唱,十四!十四!十四!
