This one is meant strictly in jest, mind you.

Paddy and Sean are laboring at a building site just across the street from a house of ill repute. Paddy looks up to see the local Presbyterian pastor skulk up to the door of the whore house, glance around nervously, and sneak inside. Paddy says, "Would ya look at that, Sean? 'Tis Reverend O'Connel. Imagine a man o' the cloth patronizin' such a place! Is there nothin' sacred these days?"

The next day, they're working away at the same location, and Paddy looks up and sees the local Rabbi hurrying into the brothel, obviously trying not to be noticed. Paddy says, "Did ya see that, Sean? Rabbi Goldberg, 'twas. Another man who's supposed to be pious, and he's goin' into a place like that! What's this world comin' to?"

Next day, same place, Paddy happens to glance up to see the local parrish Priest just as he's disappering inside the den of iniquity. Paddy stands up straight, crosses himself, removes his cap and places it over his heart, and says, "Oh dear, Sean, there went Father Flanagan. One o' those poor girls musta' died."
