http://www.adultswim.com/promos/valve/ No idea what's going on, but TF2 is somehow going to be involved in an on-air something or other it looks like. Valve has put together a number of their own productions based on the game which are viewable over at http://www.teamfortress.com/movies.php (watch the Meet the... series. It's awesome), so it's not unprecedented for them to dip into comedy-land by any means. The long-fabled Meet the Pyro is also rumored to be released soon, so this may have something to do with that. It's the final character profile in the series, so maybe they want it to be a big event when they reveal him/her?
