A week after John bought a bull, he complained to his friend, “All that bull does is eat grass. Won’t even look at a cow.”
“Take him to the vet,” his friend suggested.
A week later John reports back to his friend, and he’s much happier.
“The vet gave him some pills, and the bull serviced all of my cows!” he told his pal. “Then he broke through the fence and bred with all my neighbour’s cows! He’s like a machine!”
“What kind of pills were they?” asked the friend.
“I don’t know, but they’ve got a peppermint taste.”
