Seriously, this is hilarious.
Apparently, there was a group of D&D geeks who like play medieval battles every weekend. So a group of hipsters dressed up as zombies and stumbled out of the forest attacking the so-called knights. The zombies were victorious, but I believe this is only because the geeks had not done their homework. If they had read The Zombie Survival Guide by Max Brooks, they would have known just what to do. I would have survived.
Incidently, I find it appropriate that the hipsters were dressed as zombies. The whole shuffling together aimlessly with no purpose except to attack, while just moaning the same things as everyone else in their group must have come naturally to them. Thanks to Boing Boing for directing my attention to this one!
