An old man is selling a big cow. A young man comes to the cow and begins to look at it carefully. Then the old man goes up to him and says in his ears. "Don’t say anything about the cow before I sell it, then I will give you some meat."
一位老人正在卖一头大奶牛。一个年轻人来到奶牛旁边开始仔细地看它。老人走过去对他耳语道："在我卖掉这头奶牛前不要说任何话，过后我会给你一些肉。"
"All right," says the young man. After the old man sells the cow, he gives the young man some meat and says, "Now, you can tell me how do you think of the bad leg of the cow."
"好吧。"年轻男子说道。老人卖掉了奶牛，他给了年轻人一些肉并说道："现在你能告诉我关于这头奶牛有条坏腿你是怎么看的?"
"I didn’t find the bad leg," says the young man. "Then why did you look at the cow carefully?" asks the old man.
"我没发现坏腿呀。"年轻男子说。"那你为什么仔细地看着这头牛?"老人问道。
Then young man answers, "Because I have never seen a cow, and I wanted to know what it looks like."
年轻人回答道："因为我从未见过奶牛，我只想知道它长得什么样。"
