A rancher needs to buy a bull to service his cows but has to borrow the money from the bank. 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 serviced all my cows twice, then broke through the fence and serviced all my neighbor\'s cows three times." "Wow," says 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?" asked the banker. "I don\'t know," says the farmer, "but they sort of taste like chocolate.".
