The bartender quickly takes the bet and the owner looks at the dog and asks, Whats the thing on top of this building which keeps the rain from coming inside? The dog answers ROOF. The bartender says, Who are you kidding? Im not paying. The dogs owner says, How about double or nothing and Ill ask him something else. The bartender agrees and the owner turns to the dog and asks, Who was the greatest ballplayer of all time. The dog answers with a muffled RUTH.
