One day a rich man meets Tom. The rich man asks, “People say you are very clever(聪明的) and nothing is difficult(困难的) for you. Can you tell my why you are so clever? ” Tom answers with a smile, “Oh, I’m not clever. Instead(反而) , you are too foolish.” The rich man becomes very very angry.

Tom says, “Sir, please don’t be angry. If you don’t believe me, now let me ask you a very easy question: If you have a group(群)of sheep(绵羊), I send you another group. Then, you say, how many groups of sheep do you have?”

“Why! That’s the easiest question in the world. One and one is two. Anybody knows that. I have two groups of sheep , of course.”

Tom laughs and says, “You are wrong , Sir. Two groups of sheep put together is still one group. That’s the easiest question in the world , isn’t it?”
