I really wish they'd let him run the torch in for the 2012 Olympics. Yes, it'd be a real nerd thing, referencing a episode from over five years ago that many people don't even like (and non-fans wouldn't even get the joke and would wonder why this skinny guy in a brown coat and trainers is strutting around the stadium), but dangit, I would have actually watched the the Olympics if they'd done it! And I know they let Matt Smith run with the torch for a spell, but I don't like him, so he doesn't count.
Anyways, best of luck to the athletes, hope nobody gets accidentally hit by one of those missiles parked on the London rooftops.
