A man walks into a bar with a dog and makes the announcement that his dog can talk. The bartender tells him he's full of shit and and asks him to leave his dog outside like everyone else. The guy says "no, really, my dog can talk! I'll bet you a free beer!"
The bartender agrees, and the guy proceeds to talk to his dog...
"What's the top of a building called?"
Roof
"What's the texture of sandpaper?"
Rough
"Who's the greatest baseball player ever?"
Ruth
It's at that point that the bartender throws them both out of the bar and tells them to "stay out". The dog looks at his owner and says "should I have said Joe DiMaggio instead?"
