I'm using my backup computer with no audio so I could only imagine what he was saying, which, in my mind, was something like a backstage rant at a WWE event where a pro wrestler waxes poetic about bouncing around a ring with another wrestler.
I have to admit, upon the unveiling of the Norse hammer, knowing what a geekfest that was, numerous D&D jokes sprang to mind. Still, most of the attendees at Quakecon are requisite pc enthusiasts so they probably follow review sites and know about the spat between HardOCP and IL. So this was more of a light-hearted inside joke kind of comic relief than a calculated maneuver or childish tantrum, I think. The humor really is in imagining your sister or mother-in-law watching that going, "I don't get it.", then you can smirk and feel all elitist.
