Three Smart Dogs

Three men are in a pub bragging about their dogs. Each claims to have the world's smartest dog. The first man says, "MY dog is so smart, every morning I give him two dollars and he goes to the corner shop to buy me the Herald. He knows it's the only paper I'll ever read. He comes back with the correct change. Now that's a smart dog."

The second man says, "That's nothing. Every morning I give my dog ten dollars and he goes to the corner shop to buy me a pack of Marlboro's. He knows it's the only brand I'll smoke. He comes back with correct change. Now that's a smart dog."

The third man says "That's nothing. You know the corner shop where your dogs buy that stuff? Well, my dog runs the place!"
