He actually undid a lot of the damage he did to D&D in the modern day.Dan Harmon, one of the show's creators, is actually one of the geniuses (and voice actors) from the epic "Summoner Geeks." Many in the fanbase suspect that the books shown in the episode actually belonged to Dan Harmon.
Anyone know how I can get to see this over in the UK, tried the link but US only apparently.

This link worked for me: http://www.wisevid.com/play?v=6tbzfx8ccwt7 I don't normally drink until evening but this had me cracking open a beer. Very funny.
Also, did anyone else catch the dig at 4e in the show? "Don't we need game pieces or something?" "No, it's all in our imagination." I would've blown that off if it weren't for the fact that Harmon's a gamer. I think he was taking a potshot at 4e's reliance on minis and game tiles.
