If you had a superpower what would it be?

So I love this show called Heroes... "Ordinary People Discovering Extraordinary Abilities"

http://www.nbc.com/Heroes/

In the last episode there was this girl who remembered everything she heard, read or saw. If I could pick a super power I think that'd be it. You'd never forget anything, you could od anything you wanted because you'd know everything.

What would you pick?
