Sign of the Cross
A priest and a rabbi, who have been the best of friends for years, were always arguing the finer points of their respective theologies, trying to prove the other one was wrong.
One day as they were riding in a car, they got cut off by a drunk driver. The car flew off the road, rolled five times end-over-end, and came to rest on its roof. The priest and rabbi crawled from the wreckage and were amazed they were alive.
As the priest crossed himself, he noticed the rabbi doing the same.
The priest shouts "Praise be! You've seen the Light!"
"What?" said the rabbi.
"You -- you've crossed yourself! You have seen the True Way! This is wonderful!"
"Cross myself?? No, no, no! Not me, I was just checking that everything was still in place ... spectacles, testicles, wallet and watch."
