I've got a picture of Hellbob from when he was up on stage as a contestant in their trivia contest, and look at one of the other guys he was competing against.
"Hey, he looks kinds like mattmn!"
So I checked Mattmn's LJ from back at that date and sure enough, he was up there. I don't think I actually met Matt until at least 2 or 3 years after that weekend. Cool. Small world.
