On What TV Show Would You Want To Be an Extra

I recently learned of a Mad Men contest in which fans are challenged to submit videos of themselves doing line readings from the show to possibly win a walk-on role. How fun would that be? You'd get to wear an amazing costume and be a part of a set that is essentially transported to the 1960s.

It got me thinking about other shows that might be interesting for a fan to be a part of. Of course, it would be exciting to be on set for a filming of Lost — not just for the beautiful locale, but also to learn some of the super secretive plot points in advance. I'd be intrigued to check out Pushing Daisies and find out how much of that show is special effects and how much is actually a set. There doesn't seem to be much extra work available on The Office, but it seems like that cast has a ton of fun at work, and I'd love to be a part of that, however temporarily.

What about you? If there were a contest to win an extra role on your favorite show, would you enter it? And which show — or shows — would get you to try?
