The trope where a villain keeps someone alive because they find them entertaining or funny.
I'm specifically thinking of that time Lord Shen fromKung Fu Panda 2 says, "The only reason you are still alive is that I find your stupidity... mildly amusing" but iirc there's a whole trope page about times where people are spared because someone thing they're funny or amusing.
