Reanimated Heads

I don't quite get why those heads were still moving after they were impaled by pikes in the ground. Yeah, they're mounted by the remaining layer of neck that I guess is still there and not piercing the brain, but not one of the heads was killed by the pikes because of a careless push down on the pike? And not one of the heads that was twitching fell off of the pike because they weren't pressed down far enough? Really? --Bmax999 01:45, July 20, 2015 (UTC)
