The key to responding to an off-the-wall question is not to let it rattle you. Don't adopt a deer-in-the-headlights look if you get hit with one of these funky queries. Simply smile, take a deep breathe, and take a moment to compose your response. A little bit of silence is better than blurting out something even sillier than the question. You don't have to brilliant. You don't have to be witty. Just be yourself and give an honest response. If worse comes to worst, and you absolutely cannot think of an answer, ask if you can come back to that question later. You may lose a few thinking-on-your-feet points, but you'll gain points for handling a difficult situation with poise.
