Somehow, there should be a scene in a zombie movie with a whole bunch of zombies pursuing their prey, marching in lock step, performing the tomahawk chop, while their leader says, "you have broken the unwritten rule, you must be eaten." They could go to Citizen's Bank Park, see a bunch of Phillies fans and say, "wait, I thought you said that we'd be able to eat brains if we followed you. There's nothing to eat at CBP."
