I'm reminded of a scene in the Stephen King book "It." I don't know if it was in the movie, because I've never seen it.
Guy is in a cab, and the driver is using lots of profanity. After every sentence with a profanity in it, he'd say, "Pardon my French if you're a religious man."
At the end of the ride, cabbie asks, "By the way, are you a religious man?"
Fare: "As a matter of fact, I am." (I don't think he was; he just wanted to see what the cabbie would say.)
Cabbie: "Then get outta my cab and go to (expletive) church!"
