Talking dog

A man walks into a bar with a dog. The bartender says, "You can't bring that dog in here."
"You don't understand," says the man. "This is no regular dog, he can talk."
"Listen, pal," says the bartender. "If that dog can talk, I'll give you a hundred bucks."
The man puts the dog on a stool, and asks him, "What's on top of a house?"
"Roof!"
"Right, and what's on the outside of a tree?"
"Bark!"
"And who's the greatest baseball player of all time?"
"Ruth!"
"I guess you've heard enough," says the man. "I'll take the hundred in twenties."
The bartender is furious. "Listen, pal," he says, "get out of here before I belt you."
As soon as they're on the street, the dog turns to the man and says, "Do you think I should have said 'DiMaggio'?"

The term "the whole 9 yards" came not from football but from W.W.II fighter pilots in the Pacific. When arming their airplanes on the ground, the .50 caliber machine gun ammo belts measured exactly 27 feet, before being loaded into the fuselage. If the pilots fired all their ammo at a target, it got "the whole 9 yards".
