David Bowie – Spongebob Squarepants
Who else could get a rock legend to be the voice of a cartoon character, but Bowie’s own daughter? MSNBC reported back in 2006 that his daughter Alexandria Zahra was a big fan of the show, and the two often watched the animated series together. In Bowie’s appearance on the episode “Atlantis Squarepantis,” (which you can watch here) he plays Lord Royal Highness, the Atlantian King. Spongebob, Patrick, and the gang stumble upon him on their journey to find the lost city of Atlantis. He invites them to have a look around the city, but Spongebob is much more interested in Atlantis’ world’s oldest living bubble. They try to snap a picture of it… but it pops. Lord Royal Highness assures them that it was only a decoy, and shows them the real one… which they, too, ultimately destroy, inciting the wrath of Lord Royal Highness. Unlike most celebrity guests, Bowie managed to alter his voice and make his character sound completely different. The episode reeled in over 8 million viewers when it aired on Nickelodeon.
Glenn Danzig – AquaTeen Hunger Force
Danzig’s cameo as a shirtless, brooding, younger version of himself appears in one of the most hilarious episodes Aqua Teen Hunger Force. In “Cybernetic Ghost of Christmas Past from the Future,” Cybernetic Ghost drives Carl crazy with his incessant stories of the holiday’s true prehistoric origins, and explains that his house is built on an elf graveyard, all while filling his pool full of elf blood. Fed up with the ghost and his random, inconsistent rambling, Carl decides not to comply with the Cybernetic Ghost’s demand — to have sex with the Great Red Ape in Space — and instead puts his house up for sale… to whom? Why, The Misfits’ Glenn Danzig, of course! Danzig not only digs the house, but envisions a more demonic atmosphere with some gargoyles placed here and there, and elf blood covering the walls. Master Shake grows jealous of the quick and easy sale of Carl’s house and soon tries to sway Danzig into purchasing their very own “haunted” house — which involved Meatwad wearing a sheet and flicking the light switch on and off.
Tom Petty – King of the Hill
When a musical artist is asked to be a part of an animated series, they usually play themselves. But when it came to Tom Petty and his recurring role on King of the Hill, he opted to play the not-too-bright, but lovable, Elroy “Lucky” Kleinschmidt — the father of Luanne’s child, who lives off of a lawsuit settlement he got after slipping on urine in a Costco. He was forced into marriage, by request, when Hank and Peggy found out that he was the father of Luanne’s baby; he also found an outlet for his musical talents by playing guitar in Johnny Redcorn’s band, Big Mountain Fudgecake.
