A guy is sitting at a bar with a dog on a leash, the owner, disgruntled, walks up to him and accosts him for bringing an animal into his establishment.
"Sir, I have it clearly marked outside that no pets are to be brought into this building. I'm going to have to ask you to leave."
The dog's owner defends himself. "No, sir! You don't understand. This is no ordinary dog. He understands how to speak! I can demonstrate it to you."
The owner of the bar is losing his patience but allows him to continue.
The man asks his dog. "Hey sparky! How's life?"
The dog answers "Ruff."
"What's on top of the house?" "Ruff." "Who's the greatest baseball player of all time?" "Ruff."
The bar owner is not impressed. He gets up, grabs the man by his shoulders and launches him through the door, with him landing in a pile out in the street.
The dog comes trotting up to him and says:
"Yeah, so for that last one do you think I should have said DiMaggio?"
