　　Mr. Smith s bad tooth hurts(疼痛) this week. He can't eat any food and he can't sleep in the night. So he often feels tired when he is at work. He can hardly (几乎不) stand (忍受) it any longer. Sometimes his wife has to sit on the bed with him and she says to him this afternoon, “Go to see a dentist(牙科医生), Dave. I think he can help you.”

　　“But he wants 200 dollars for it.” Says the man. “I don't have enough money, you know.”

　　“I find some money in the drawer(抽屉). You can go to the dentist with it. Look! Here it is.”

　　When he sees the money, Mr. Smith is very happy. But after he looks at the money carefully, he feels very worried. He says, “It's fake(假的). How can I give fake money to the dentist?”

　　“It doesn't matter,” says his wife. “Maybe the dentist doesn't know about it. ”

　　Mr. Smith thinks that his wife may be right and he agrees with her. He goes to ask the dentist to fill his tooth. But when he gives the money to him, the dentist finds all the money is fake. He is very angry and takes him to the police office.

　　“Why do you use the fake money, sir?” a policeman asks Mr. Smith.

　　Mr. Smith thinks for a few minutes, and then he answers, “But the tooth he fills for me is false, too!”
