A guy walks into a bar with his dog. The bartender immediatly says, "Buddy, we don't allow dogs in here."
The man replies, "but this isn't an ordinary dog- this dog can talk. If I can prove it, can he stay?"
So the bartender agrees that if the man can prove that the dog can talk, he can stay.
The man turns to the dog and says, "What does sandpaper feel like?"
The dog replies, "Rough!"
The bartender doesn't fall for it and tells the man to try again.
The man again turns to dog and this time asks, "What is on top of a house?"
The dog replies, "Roof!"
Now the bartender is getting agitated and tells the man to get out. But the man is able to convince the bartender to give him one more shot.
This time the man asks the dog, "Who is the greatest baseball player ever?"
The dog replies, "Ruth!"
The bartender has had enough and throws the man and the dog out of the bar.
Laying on the street outside the bar, the dog turns to the man and says, "Should I have said Dimaggio?"
