The farmer complained that the bull just ate grass and wouldn't even look at a cow.
Banker Bill suggested that he have a veterinarian take a look at the bull. Next week, Banker Bill 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 Banker Bill, "what did the vet do to that bull?"
"Just gave him some pills," replied the farmer.
"What kind of pills?" asked Banker Bill.
