When Zombies Attack

You walk up to the other door and give 'er a twist, and it comes open easily. You poke your head around, and are greeted with a view full of irony: A zombie was running around with a gun, while a (at least he looked regular...) man was on his back, biting and clawing the zombie. "OK..." you say to yourself, "Whatever I was expecting, I wasn't expecting that."
