I'm suprised no one else mentioned it, then again maybe they did and I skimmed past it. There was another episode of X-Files once where the psycho the picked up made a reference to DnD, something like,
"I didn't play Dungeons and Dragons for so many years and not learn something about courage..."
I didn't know whether to be impressed that it wasn't a completely negative reference of pissed that the reference was made by a complete nut. oh well, stero types happen in all areas of life, and I guess we gamers get an easy time than many due to them...
On a side note about sterotypes, the guys at school who used to get a real hard time for being geeks didn't even play D&D as far as I know. The guys I used to play with at school were all the druggies and dope fiends of my school, who looked more like gothics and bikers than geeks. Since leaving school, the people I've gamed with have ranged from bikers, hippies, cool designer types of the in scene, programmers, a psychiatrist, some brickies labourers (big fellows), homies, a good number of girls included, and the CEO of my company (granted it is a games company

).
Very few of them could come close to being labelled a sterotypical geek, though many are self proclaimed ones. As for myself, my girl friend accuses me more of being a yuppie than a geek.

::Sigh:: so many sterotypes...
