This is what it was like to be a real nerd, back in the '80s, before the word 'nerd' got co-opted by hipsters. Everyone's a nerd now, but you aren't a real nerd until you get your ass kicked on a daily basis for the stuff you like.
From Ethan Gilsdorf, the guy who shot this video: It's 1981, and yes, this is poorly shot. But this is an actual (silent) movie from a real Dungeons & Dragons session back in 1981, shot by Ethan Gilsdorf, author of Fantasy Freaks and Gaming Geeks, on Super 8 (back when I was about 15). This takes place on a Friday night in Lee, New Hampshire. Look for the classic Mountain Dew can at 1:53.
