A cattle rancher needs a bull to service his cows, but needs to borrow the breeding fee from the bank. The banker lends him the money and 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 tells the farmer that he knows a great veterinarian, and he'll send him out the next day to check out the bull.
The next week the banker stops by to see if the vet helped. The farmer looks very pleased and tells the banker, "The bull has serviced all my cows, broke through the fence and even serviced all my neighbor's cows."
"Wow," says the banker. "What kind of pills ?" asks the banker. "I don't know," says the smiling farmer, "but they sort of taste like peppermint."
