(With thanks to my namesake, Bev, for telling me.)

There is an ecumenical convention of clergymen at which a rabbi and a priest have become friendly.  A chorus of young school children entertains the group and afterwards there is a break.

The priest says to the rabbi, "Hey, do you want to have some fun?", pointing to the school children.  "What do you mean?", says the rabbi, puzzeled.  "Come on, you know what I mean." ,says the priest winking.  The rabbi still professes confusion at what the priest is suggesting.  Finally the priest, in exasperation, blurts out:  "I talking about going over to those kids and giving them a good fucking."

"What the hell are you talking about?" says the rabbi.  "Those kids don't have any money."

ba-doom.

LOL, I heard it differently, twas a priest and a lwayer walking side by side, the priest spotted a lovely blonde and whispered "boy, I'd like to fuck her". The lawyer answered, "out of what?"
