In the same comment, Mike Judge explained how South Park creators Trey Parker and Matt Stone actually met Isaac Hayes at the premiere of Beavis and Butt-Head Do America. Since Hayes recorded the song for the film’s opening credits, he performed the song at the premiere.
Judge had also invited Parker and Stone to the premiere. While South Park hadn’t yet been made into a show, her short The Spirit of Christmas, which was the early template for the making of her upcoming show, was essentially doing the rounds in Hollywood, which was a protoviral video. Beavis and Butt-Head creator Mike Judge befriended the duo, which led to their invitation.
At the premiere, Parker and Stone actually met their future chef. The judge recalled, “I don’t think it had anything to do with them [casting Hayes]. I think when they started South Park, that was just the normal casting process.” While meeting Hayes at the premiere didn’t get him the job on South Park, Parker and Stone definitely must have had it on his back have their thoughts when it came time to cast someone for the chef’s voice.
Judge then voiced Kenny in the 1999 film adaptation South Park: Bigger, Longer, & Uncut, where the character was actually allowed to speak rather than being a muffled voice under a cloak. Now, Judge, Parker and Stone have all signed deals with Paramount+ to produce new episodes and movies of South Park and Beavis and Butt-Head. It’s a great time to be a fan of 90’s adult animation right now.
