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!

一個人在精神病院的木圍墻外路過,聽見里面所有的人在唱,十三!十三! 十三!

他很好奇,就找到圍墻的一個洞,然后看進去。突然有個人捅到了他的眼睛。

然后里面所有人開始唱,十四!十四!十四!
