A farmer needed to buy a bull to service his cows but, in order to afford it, he had to borrow money from the bank. The banker who lent him the money stopped by a week later to see how his investment was shaping up. The farmer complained that the bull just ate grass and wouldn't even look at the cows, so the banker suggested calling in a vet to take a look at the animal.

The following week the banker returned to see if the vet had been of any use. The farmer looked very pleased. "The bull serviced all my cows twice," he said, "then broke through the fence and serviced all my neighbor"s cows three times."

"Wow!" exclaimed the banker. "What did the vet do to that bull?"

"Just gave me some pills to give him," replied the farmer.

"What kind of pills?"

"I don"t know," said the farmer, "but they sort of taste like chocolate."
