An Amazing Talking Dog

A man and his dog walk into a bar. The man proclaims, "I'll bet you a round of drinks that my dog can talk."

Bartender: "Yeah! Sure...go ahead."

Man: "What covers a house?"

Dog: "Roof!"

Man: "How does sandpaper feel?"

Dog: "Rough!"

Man: "Who was the greatest ball player of all time?"

Dog: "Ruth!"

Man: "Pay up. I told you he could talk."

The bartender, annoyed at this point, throws both of them out the door. Sitting on the sidewalk, the dog looks at the guy and says, "or is the greatest player Mantle?"
