Peppermint Anyone?

A farmer went to the local bank to borrow money for a new bull. The loan was made and the banker, who lent the money, came by a week later to see how the bull was doing. The farmer complained that the bull just ate grass and wouldn't even look at a cow.
The Banker suggested that he have a veterinarian take a look at the bull. Next week, the Banker returned to see if the vet had helped. The farmer looked very pleased. "The bull has serviced all of my cows! He broke through the fence, and bred all my neighbour's cows! He's been breeding just about everything in sight. He's like a machine!"
"Wow," said the Banker, "what did the vet do to that bull?" "Just gave him some pills," replied the farmer. "What kind of pills?" asked the Banker. "I don't know, but they kind of taste like peppermint."

I'd give the joke a 4, but the odd banner ad a 6 :)
