A Jewish couple had a son who was . . . well . . . a holy terror. By the time for his bar mitzvah, he'd been kicked out of every school they put him in. Desperate, the parents went to the rabbi for advice. The good rabbi stroked his beard and meditated. Finally, he told them to enroll the boy in Catholic school.
The shocked parents did as their rabbi directed and took their son to the nuns at St. Jude’s and left him.
After school, the son came home and said, "Good afternoon, Papa. Good afternoon, Mama."
The young man went to the table and did on his homework. The parents looked at each other in amazement, afraid to speak. The mother wrung her hands and the father twisted his beard all the while their boy helped serve the evening meal, bowed his head for prayers of thanks, and even helped with the dishes.
No longer able to contain himself, the father asked, “We’re ever so grateful, my son, but what in Moses’s name did they do to you?”
"Papa, when you left, the nun took me from class to class all day, each time saying they knew how to deal with rowdy boys. Those Catholics mean business! They got some Jewish-looking guy nailed up on boards in every room!”
