Unfortunately, zombies couldn't eat their parasitic brains because a bizarre, energized, enigmatic void swept through the entirety of all known and
unknown universes in all possible times, spaces and dimensions and made it impossible for a zombie or the thought of a zombie to ever exist in any
possible way.
Fortunately, the zombie killing thing that made zombies impossible to exist was only a nightmare of a particular zombie named Jimmy Bob. These
nightmares were caused by the fact that this zombie had a parasite in his brain that would allow him to live for only five and a half more weeks.
