On January 20th, 1982, Ozzy Osbourne famously bit the head off of a bat during a show in Des Moines, Iowa.
A fan had thrown the bat on stage and, stunned by the lights, it laid motionless.
The Prince of Darkness thought it was fake so he picked it up and attempted to bite its head off but the bat started to flap its wings and Ozzy realized it was real.
The rocker wound up being rushed to a hospital and was forced to get a series of rabies shots.
