From Minecraft to Pokémon, no franchise is too big or beloved to get the Honest Game Trailers skewering. Step right up Valve ("the company who realized it's way easier to sell other people's games than create their own,") it's Team Fortress 2's turn in the barrel.
Everything and everyone gets beaten up pretty good — Scout is "the ShamWow guy," Pyro is "for players who don't like to aim." (and Engineer "for players who don't like to play.") Hats and virtual crap also figure prominently. Naturally, it closes out with some numerology.
For more of the Honest Trailers series, this link has the entire run, spanning 16 episodes so far.
