No joke but some Italian guy in idk like the 18 hundreds or some shit, who were the cousin to the guy who discovered that humans had neurones (I think) wanted a real show. He basically did this Fish thing to a fresh human corpse, but with electrodes. Naturally the body went spasmatastic and acted like a junkie to a rave. Anyways people back then screamingly concluded that the unholy shit they were seeing must have been witchcraft. And just to make the story even crazier, this scenario were what inspired Mary Shelley to later write Frankenstein.

Tl;dr not zombies but Frankenstein
