I would revive Thomas Paine. So I can watch/read/take part in what would come after. Harold Camping (he's the latest rapture guy right?), because he's close enough to death to be more of a mercy than anything else. In fact, I'd go with the United States of America's Founding Fathers, each for every tyrant or potential tyrant until they were all back just to see their individual reactions while I ate popcorn.
