For 2008, I choose:
Illinois Governor Rod Blagojevich!!
First, let me study the patterns in the potato chip crumbs at the bottom of my Jimmy John's sandwich wrapper, which reveals that in 2009:
Aliens will spirit Blago from a prison cell, replacing him with a standard model Contrition-bot. Aboard the mothership, advanced neuro-empatho-surgical techniques and smoke box narco inhibitors will turn his thuggish malice and narcissism into a diamond-hard stoic evil. Once that process is complete, he's be dropped through a time chute into the past to shape human civilization for the coming alien invasion.
Yes, Rod Blagojevich will become...
Really, it's obvious when you think about it. .
