I'm not sure where I read it, it was a while ago, but apparently the US Military has a plan for coping with the Zombie Apocalypse - should it happen. The plan's disclaimer specifically states that "this plan was not actually designed as a joke". CONOP8888 - otherwise known as "Counter-Zombie Dominance" (dated April 30, 2011) was devised to allow the military to come up with a way to plan what could be a real response using a fictional scenario. That was the plan anyway. You can read more in The Washington Post - just search Google for "Leaked Document Reveals Government Preparing for Zombie Apocalypse".
