Whether its a bunch of tabletop Dungeons and Dragons players or a bunch of extreme Guild War MMORPG players, role-players are generally just nuts. Have you seen the costumes people wear at Blizzcon? I mean talk about "mom's basement" scary.

Matt Burnett and Ben Levin from For Tax Reasons knew this already, and created a role-playing themed cartoon for the holiday season that spells out the disaster that is public theater and LARP players.
Watch "IM IN UR MANGER KILLING UR SAVIOR" on the video screen above, and look for the Final Fantasy and Army of Darkness references.
