A farmer needs a bull to service his cows, but needs to borrow the money. The
 banker who lent the money comes by a week later to see how his investment is
 doing. The farmer complains that the bull just eats grass and won't even look
 at the cows. The banker suggests that a veterinarian have a look at the bull.

 The next week the banker returns to see if the vet helped. The farmer looks
 very pleased.

 "The bull has serviced all my cows, broke through the fence, and has serviced
 all my neighbors cows," say the farmer.

 "Wow," says the banker. "What did the vet give the bull?"

 "Some pills," replied the farmer.

 "What kind of pills?" asked the banker.

 "I don't know," says the farmer, "but they sort of taste like peppermint..."
