A priest goes to the mechanic

He tells the mechanic, "hey, I just brought in my car last week, and since you guys worked on it, it's leaking oil all over my garage." The mechanic says, "my apologies father, we'll make sure we get it right this time, come back tomorrow, and we'll have it tip-top for you." The priest returns the following day, and he says, "well, how is it?" The mechanic says, "we found the issue. it was a loose oil filter, and it won't be leaking again because I screwed it in tighter than a nun's cunt." Solemnly, the priest looks the mechanic dead in the eye, and says, "better give it another quarter turn."
