A poor farmer finds a genie lamp

The genie appears before him and declares "I am a powerful genie! Due to budget cuts, I will only be granting one wish, but you can wish for anything you desire and I shall make it come true!"

The farmer wastes no time. "My neighbour, Peter, was once as poor as me. One day, he received a cow as a gift, and he began to sell the milk. Suddenly, he is earning twice as much. He could afford to fix the roof, he bought new clothes, and he even took a day off to have wild sex with his wife. That cow made his life so much better than it was before."

The genie nods. "I see. So, your wish is..."

"Kill his cow."
