This isn't meant to be offensive to either party by the way, it could be anybody.
A priest and a rabbi are driving along in a car, on the way to a religion trade show. As they drive along the mountain road, the rabbi loses control of the car, and careens into the mountain, completely and utterly destroying the car. Amazingly, the priest and rabbi climb out of the smouldering wreckage, completely unharmed.
The priest says to the rabbi, "Look! The car is totally destroyed. We, however, are unharmed. Surely this is a sign from above that we are chosen, that we will serve a great purpose in life."
The rabbi agrees, and sees an unopened bottle of brandy roll out of the wrecked car. "Look! This bottle of brandy isn't even scratched! Surely those watching over us want us to drink this brandy in celebration".
"Absolutely!" says the priest.
The rabbi slugs down 1/2 the bottle. He hands the other half to the priest, who doesn't drink his half.
The rabbi says, "Aren't you going to have any?"
The priest says to him, "No thanks. I think I'll wait for the police to arrive"
