One of the many variations on an old joke:
A guy takes his dog to an entertainment agent, claiming the dog can talk.
The agent says “Sure he can. Okay, let’s hear him”.
So the guy asks his dog, “How was the road coming into town today?”
“Rough,” barked the dog.
“Continue”, says the agent.
“What do we have over our house?”
“Roof,” barked the mutt.
The agent says “They sound like barks to me”.
The guy was disappointed, but persevered.
“All right,” he said, “this time you pick out the topic. Ask me to ask him about anything.”
The agent said “Okay. Ask him something about baseball.”
“Who,” the dog was asked, “was the greatest ballplayer who ever lived?”
“Ruth,” barked the dog.
“Get out!” barked the agent.
As the pair was walking out, the guy says to the dog, “Well, you really did it to me this time.
The dog’s tail stops wagging, and the dog looks up at the guy and asks “Do you think I should have said Gehrig?”
