ELVIS if you look on Wikipedia you'll find a list of every winner. If you watch the race on The BBC on April 14th, you'll see who wins this year's. Hope that helps...
stain removal questions seem to go to Home & Garden, though I agree it isn't a perfect fit (of course, if you live in your jeans...). For Grand National questions, try Sport. For information about the future, Religion & Spirituality. All humorous answers should be detached from the questions and moved to Jokes.
I like jno's idea.....we should take all the (often unitentionally) funny replies and slap 'em in their very own category. What a fun couple of hours that'd be, trying to match the answers to the questions that are distributed throughtout the site ;-)
