I admit I'm not a regular MGHSHr watcher, and apologies if I missed this in the thread, but for the HS portion, I'm noticing that for the "either-or" questions, when one option sounds a little more outrageous or out of left field, you should go probably with that answer.
One question tonight asked whether you should use Vaseline or lard to get grass stains out of your clothes. The celebrity said Vaseline; it was lard.
