One day a rich man met Sam on the road. The rich man said to Sam, "I hear you are very clever, but I don't believe." Sam answered with a smile,"Oh, I am not clever, instead, you are silly." The rich man was angry, but Sam said, "Don't be angry. Now let me ask you a question. If you have a group of sheep, and I give you another group of sheep, how many groups of sheep do you have?" The rich man answered, "Oh! That's easy . I have two groups of sheep." Sam laughed and said, "You are wrong. Two gruops of sheep put together is still one group. That's easy!"

一天，一个富人在路上遇到萨姆。富人对萨姆说，“我听说你很聪明，可是我不相信。”萨姆笑着答道：“噢，不是我聪明，而是你太笨。”富人生气了，可是萨姆说，“不要生气，现在我问你一个问题。假设你有一群羊，我又给你一群羊，你有几群羊?”富人回答：“啊，这太简单了，我有两群羊。”萨姆哈哈大笑，“你错了，两群羊放到一起还是一群羊。这太简单了!”
