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!"
