As a kid, one of my favorite misdirection groaner versions of this type of puzzle started with “Ok, you’re [or I’m] driving a bus. At the first stop X amount of people get on. At the next stop, half the people get off, and 3 people get on.” And then you just spin in with some types of seemingly complicated, but doable math for a couple rounds. At the end, the question is “what is the name of the bus driver?”
Well, it’s there in the first sentence.
My father drove me nuts, because I’ve heard my father tell that riddle, and completely forget the first sentence as, you know, kinda being the key to it all, so it just ended up completely non-sensical in the end. Or maybe he was trying to some abstract Kaufmann shit, I don’t know.
