My father in law was a proctologist - and also a man I didn't really enjoy spending any time with. One day during one of those strained compulsory family dinners - not sure which, maybe Thanksgiving - he turned to me and said with this false jovial air:
"Hey, you're a computer guy. I have this problem with my Windows laptop. Could you take a look?" and proceeded to unpack his laptop, which he had brought along, clearly to have me fix it.
So I got up, started undoing my fly and said "Sure! Hey, I have piles. Could you take a look?"
He got up and left without a word, and never came back. His wife kept visiting though, thankfully. She was lovely. But I got rid of him for good that day. But I did have to face the music with my wife 🙂
