Thirteen! 十三!

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

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!"
