A Smart Talking Dog

A man & 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 & says, "or is the greatest player Mantle?"
