A priest and a rabbi lived next door to each other. Whatever one did, the other had to do better. The priest got a new lawn mower. The rabbi got a new riding lawn mower. The priest got a satellite dish. The rabbi got a motorized one. The priest bought a Mercedes. The rabbi bought a Rolls-Royce. The priest stood in front of his Mercedes, sprinkled holy water on it, and blessed it. The rabbi cut six inches off the Rolls' exhaust pipe.
