"Humor: Not an accusation, just evidence" joke

Source unknown.
This bishop invites a young priest over for dinner. During the meal,
the priest can't help noticing how attractive and shapely the
housekeeper is. Over the course of the evening he starts to wonder if
there's more between the bishop and the housekeeper than meets the eye.
Reading the young priest's thoughts, the bishop volunteers, "I know what
you must be thinking, but I assure you, my relationship with my
housekeeper is purely professional."
About a week later the housekeeper comes to the bishop and says,
"Excellency, ever since the young Father came to dinner, I've been
unable to find the beautiful silver gravy ladle. You don't suppose he
took it, do you?"
The bishop says, "Well, I doubt it, but I'll write him a letter just to
be sure." So he sits down and writes: "Dear Father, I'm not saying that
you 'did' take a gravy ladle from my house, and I'm not saying you 'did
not' take a gravy ladle. But the fact remains that one has been missing
ever since you were here for dinner."
Several days later the bishop receives a letter from the young priest,
which reads: "Your Excellency, I'm not saying that you 'do' sleep with
your housekeeper, and I'm not saying that you 'do not' sleep with your
housekeeper. But the fact remains that if you were sleeping in your own
bed, you would have found the gravy ladle by now."
