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."
