This is one of my favorite jokes, I think my (Jewish) mother told it to me first. A Catholic priest, an Imam, and a Jewish rabbi are all talking to each other. All 3 of the men have had problems with rats at their place of worship, and they're discussing how they've dealt with them.

The priest says, "I caught them, put them in a box, and dropped them off ten miles away- but they still came back!"

The Imam says, "I caught them, put them in a box, and dropped them off fifty miles away- but they still keep coming back!"

The Rabbi says, "I gave each rat a Bar Mitzvah, and they haven't come back since!"
