One day an old man is selling a big elephant. A young man comes to the elephant and begins to look at it slowly. The old man goes up to him and says in his ear, “ Don’t say anything about the elephant before I sell it. Then I will give you twenty dollars.”“All right,” says the young man. After the old man sells the elephant, he gives the young man twenty dollars and says, “ Now, can you tell me how you found the elephant’s bad ears?”“ I didn’t find the bad ears,” says the young man. “ Then why are you looking at the elephant slowly?” asks the old man.
