I was looking at this page about the excavation of an old WW1 tank and got a great idea for a short horror story. I love generic zombie flicks like Nightmare City, Zombie Lake (not safe for work) and Shock Waves. So what if they dug up some old German tank full of dead nazi soldiers that were part of a weird war experiment. The tank would be left in a storage building over night at which time the nazi zombies would wake up, drive their tank through the wall, then start kicking nazi zombie ass all over the place. I don't know where it would go from there but man that's a good fucking start.
edit - I love the idea of Hitler's brain still being out there somewhere, presumably locked up in a Russian vault that nobody knows about. So maybe these nazi zombies can sniff that brain out and by eating it they become SUPER NAZI ZOMBIE SOLDIERS! Just when you thought things couldn't get any worse! And let's assume somewhere underground there's hundreds of thousands of nazi zombies that are trapped due to a cave in caused by allied bombings. Well at some point those mothers are going to get loose!
