A guy buys a new Lamborghini sportscar and goes to his Orthodox
rabbi to ask him to bless a mezuzah for the car.
“What is a Lamborghini?” asks the rabbi and when the guy explains, the rabbi says “No way am I
blessing a mezuzah for such an extravagance!”
So the guy finds a Conservative rabbi and makes the same request. “What is a Lamborghini?”
the rabbi asks and hearing the explanation, also refuses to give his blessing.
So finally the guy goes to a Reform rabbi with his request.
“Sure!” says the rabbi, “but what’s a mezuzah?”
