A man walks into a bar with a dog. The bartender says, "You can`t bring that dog in here." "You don`t understand," says the man. "This is no regular dog, he can talk." "Listen, pal," says the bartender. "If that dog can talk, I`ll give you a hundred bucks." The man puts the dog on a stool, and asks him, "What`s on top of a house?" "Roof!" "Right. And what`s on the outside of a tree?" "Bark!" "And who`s the greatest baseball player of all time?" "Ruth!" "I guess you`ve heard enough," says the man. "I`ll take the hundred in twenties." The bartender is furious. "Listen, pal," he says, "get out of here before I belt you." As soon as they`re on the street, the dog turns to the man and says, "Do you think I should have said `DiMaggio`?"
