Rabbi Levy had to spend time in a Catholic hospital recovering from a painful fall. He became friends with the sister who was a nurse there. One day, she came into his room and was surprised to see that the crucifix on the wall was missing.
She asks him good-naturedly, “Rabbi, what have you done with the crucifix?”
“Oh, sister,” chuckled Rabbi Levy, “I just figured one suffering Jew in this room was enough.”
