There was a guy who went into a shop to buy a parrot. There were three parrots in the shop. One was $5,000; another one, $10,000; and the third one, $30,000. The customer asked the owner,

　　“How come this guy is $5,000? That’s so expensive for this kind of parrot.” The owner said, “Because I have trained him and he can talk.” So the customer asked him, “How about this guy?

　　What can he do that makes him so expensive?” The owner said, “Well, apart from talking, he can also do some amusing actions,like dancing and so on. That’s why he’s so expensive.”

　　Then the customer said, “How about the third one? What can he do that makes him so expensive?” The owner of the shop said, “I don’t know. Normally, I have never heard him talk, nor dance, nor whistle, nor sing, nothing at all!

　　But the other two call him ‘The Boss.’”

　　有个人到一间商店买鹦鹉。店里有三只鹦鹉，其中一只卖五千元，另一只卖一万元，还有一只卖三万元。顾客问老板：「为什么这只要卖五千元？这个价钱对这种鹦鹉来说太贵了！」老板说：

　　「因为我有训练他讲话。」顾客又问：「那这只呢？他会做什么？为什么要卖这么贵？」

　　老板说：「他除了会说话之外，还会表演一些有趣的动作，好比说跳舞等等，所以才卖这么贵。」

　　顾客接着又问：「那第三只呢？他会做什么？为什么要卖这么贵？」

　　老板说：「我不知道。我从没听过他讲话、吹口哨或唱歌，也没看过他跳舞，什么都没有！不过另外两只叫他：『老板！』」
