LORd--I think I know the one you're talking about. They released that as a trailer for Summoner, as well.Originally the dialogue comes from an old radio sketch by a group called the Dead Alewives, that was on the Dr. Demento show, I believe. It's the one with the "I cast Magic Missle on the DARKNESS," right? Anyway, yeah, that's the origin of that particular thingy, and there was a followup sketch that involved turning one's bag of holding inside out to walk through walls, another common PnP RPG joke.
