     One day a rich man met Sam. The rich man asked, "I hear you are very clever and nothing is difficult to

you. Can you tell me why you are so clever?"

     Sam answered with a smile," Oh, I am not clever. Instead you are too foolish (愚蠢的)." The rich man

became very angry.

     Sam said," Please don't be angry. If you don't believe me, now let me ask you a question. If you put one

group of sheep and another group of sheep, how many groups of sheep do you have?"

    "Why! That's an easy question. One and one is two, anybody knows it. I have two groups of sheep."

    Sam laughed and said," You are wrong. Two groups of sheep put together is still one group. That's the

easiest question in the world."
