Talking Dog

A man auditions for a late-night variety show...he shows up with his "talking dog". The host, while skeptical, asks for a demonstration.
The man says" What's the texture of sandpaper?"
The dog says "Ruff".
Man says, "What's on top of your doghouse?"
Dog says, "Roof".
Man says "Who's the greatest baseball player of all time?"
Dog says "Ruth".

The talk show host has had enough. "SECURITY!" GET THESE TWO BOZOS OUTTA HERE!" The man and his best friend are heaved unceremoniously into the street. The man gets up, dusts himself off, and shoots the dog a look that would fry an egg.
The dog says, "What......? I shoulda said DiMaggio?"
