Whovians (and before that Doctor Who). There were mentions of the passing of Ian Cullen that occurred a couple of months ago (he was interviewed on the first episode of Whovians); as well as the mention of Sacha Dhawan who played original director Waris Hussein in "An Adventure in Space and Time" played The Master in the episode.
I only really watch the big games, and this was an entertaining one. Thought it was over when the Chiefs got that pass reversed, but then they came back with a longer drive, rallied hard, and just piled on at the very end. Nice to see Reid get a Super Bowl after 2005, in any case.
