到底是绳子还是公牛 Rope or Ox  

Rope or Ox?
绳子还是公牛？
The man in the prison asked a new er why he was sent there. The new er answered
" I am out of luck
I think. A few days ago I was walking in the street when I saw a piece of dirty rope. I thought nobody wanted it and so I picked it up and took it home."
在监狱里，一个人问新来的犯人为什么被关进来。新来的犯人回答说：“我想我真是倒霉。几天前我在街上走的时候，看到一根脏绳子，以为没人要了，便捡起来带了回家。”
"But it is not against the law to pick up a piece of rope and take home."
"I told you I had bad luck
didn't I?" the man sighed
"The trouble is that I didn't notice there was an ox at the other end of that rope."
“我告诉过你我倒霉了吧？”那个人叹了口气，“麻烦的就是我没有注意到绳子的那一头还有一头公牛。”
