what's the most annoying question you have been asked during an interview?

Several years ago when I was applying for a job at McDonald's, the manager asked me "If you saw an elephant dressed in plaid pajamas stuck on a tree, what would you do?" It completely threw me off because I have never gotten a question like that before. I didn't even realize it was a thing. I understand now that the purpose of such questions is to see how quickly you can think on your feet, but for Christ sake, it's a McDonald's job. I was trying to flip some meat patties for minimum wage, not apply for a lawyer position at a major firm. That is the only time I have ever gotten such a ridiculous question, but anything of that mold I would find very annoying. Worse yet if it's a low-skill position. Like, really? lol.
