The Oz Fest of 3001 was a rock performance held in honor of the deceased Ozzy Osbourne, at which the ghost of Ozzy Osbourne was in attendance.
Slash Glorgson performed at the concert with an unknown band, and commented that it wasn't "what it used to be since Ozzy died." During the event, Slash's son, Oliver the Fifth, previously raised by his grandmother Rose Cotton, showed up against Rose's wishes to be reunited with his father.
Rose showed up to scold him, only to be possessed by Ozzy's ghost and hand her title of mayor of Little Hillbillytown to Slash.
The concert ended with the audience falling into a pool of quicksand.
Oz Fest 3001 appeared in the third season of the show Weirdoes:
