South Park can turn current events into an episode within days, but some of its strangest stories happened offscreen. Trey Parker modeled Kenny on a childhood friend, George Clooney barked as Stan’s dog, and a Colorado restaurant added staff when Comedy Central reran its episode. The show also faced battles over profanity, Scientology, and censorship. These 50 facts reveal the people, production choices, and real events hidden behind the jokes.
1 Kenny McCormick’s Orange Parka Origin
South Park co-creator Trey Parker based Kenny McCormick on a childhood friend named Kenny, the poorest kid in his neighborhood. The boy wore an orange parka that muffled his voice and frequently skipped school, prompting Parker and his friends to joke that he had died. He would return several days later, inspiring the character’s repeated deaths and unexplained reappearances.
2. After South Park aired “Chef Aid” on October 7, 1998, the term “Chewbacca defense” entered the legal lexicon for a strategy that deliberately confuses a jury instead of refuting the opposing case. The episode parodied American lawyer Johnnie Cochran by having him argue that Chewbacca’s supposed decision to live among the Ewoks made no sense, so the jury had to acquit his client. Lawyers already recognized such distractions as red herrings or irrelevant conclusions, but South Park gave the tactic its memorable name.
3. South Park co-creator Trey Parker begged executive producer Anne Garefino not to air “Make Love, Not Warcraft” because he feared the episode would ruin the show’s legacy. Convinced that he had lost his touch, Parker went home depressed and unable to sleep. The episode instead earned critical acclaim, became a fan favorite, and won a Primetime Emmy Award.
4. Before South Park aired “Le Petit Tourette” in 2007, the Tourette Syndrome Association, now called the Tourette Association of America, expected the episode to offend and insult people with the condition. After watching it, the organization praised the episode as surprisingly well-researched and said it conveyed a considerable amount of accurate information. Its main criticism concerned the exaggerated focus on coprolalia, or involuntary swearing, because 85 to 90 percent of people with Tourette syndrome do not experience it.
5. The real Casa Bonita restaurant in Lakewood, Colorado, had to track whenever Comedy Central scheduled South Park’s “Casa Bonita” episode so managers could increase staffing for the resulting crowds. The 2003 episode followed Cartman’s desperate attempt to attend a birthday party at the restaurant. Its reruns generated enough extra business that a television schedule became part of Casa Bonita’s staffing plans.
6 Fox Rejected South Park’s Hankey
Fox refused to move forward with South Park after creators Trey Parker and Matt Stone rejected its demands to remove Mr. Hankey, a talking piece of feces. They took the series to Comedy Central, where it debuted in 1997, and became the network’s most successful show within three months. Its popularity helped expand Comedy Central’s reach from 9.1 million households in 1997 to 50 million by June 1998, making it one of America’s fastest-growing cable channels.
7. American singer and actor Isaac Hayes, who voiced Chef, did not personally quit South Park, according to his son, Isaac Hayes III. After Hayes suffered a stroke and lost his ability to speak in January 2006, Parker and Stone received a resignation statement and initially believed he had chosen to leave the show. Hayes III later said his father’s Scientologist assistants controlled his affairs and that one of them apparently resigned from the show on his behalf, possibly without Hayes’ knowledge.
8. Comedy Central originally wanted South Park creators Matt Stone and Trey Parker to remove Timmy Burch, fearing controversy over the inclusion of a disabled child character. Parker and Stone fought to keep him because the other children treated Timmy as an equal rather than excluding or ridiculing him for his disability. The network relented, allowing Timmy to become a recurring South Park Elementary student.
9. In sixth grade, South Park co-creator Trey Parker wrote and performed “The Dentist,” one of his earliest productions, for his school’s talent show. The sketch showed a dental procedure going disastrously wrong and used so much fake blood that kindergarten students in the audience started crying and panicking. School officials called Parker’s parents.
10. During potty training at around age four, South Park co-creator Trey Parker often refused to flush the toilet. His father, geologist Randy Parker, called the stool “Mr. Hankey” and warned that it would come alive and kill Parker if he left it unflushed. The frightened child began flushing repeatedly and later transformed the childhood threat into Mr. Hankey, the Christmas Poo.
11 Sia Secretly Voiced Randy’s Lorde
In 2014, South Park secretly recruited Australian singer Sia to provide Randy Marsh’s polished vocals as Lorde on “Push (Feeling Good on a Wednesday).” South Park co-creator Trey Parker wrote the parody song, while Sia recorded it without receiving an on-screen credit. She worried that the joke might offend New Zealand singer Lorde but proceeded because she thought Lorde would find it funny, admitting, “I felt bad, but I went ahead and did it anyway.” Lorde later reacted positively to the parody.
12. South Park’s 2017 role-playing game was originally titled South Park: The Butthole of Time. Ubisoft told creators Trey Parker and Matt Stone that retailers would refuse to stock a product with “butthole” in its title. Parker spent hours rearranging the word until he found a way to hide it in plain sight with South Park: The Fractured but Whole.
13. South Park: Bigger, Longer & Uncut repeatedly received an NC-17 rating from the MPAA because of its relentless profanity, with one widely cited tally counting 146 uses of “fuck.” The ratings board warned that a script exceeding 400 swear words would receive an NC-17, so creators Trey Parker and Matt Stone stopped at exactly 399. After the MPAA returned an NC-17 rating five times, executive producer Scott Rudin intervened, and the board approved the film’s original cut with an R rating.
14. In 2007, South Park creators Trey Parker and Matt Stone negotiated a landmark deal giving them a 50-50 split of Comedy Central’s digital revenue from the series. As streaming increased the value of South Park’s library, those rights strengthened their position in later negotiations. In 2021, the pair signed a six-year ViacomCBS agreement reportedly worth $935 million to continue the show through 2027 and produce 14 projects for Paramount+, making it one of television’s richest deals.
15. In 2005, New Zealand singer Wing appeared as a version of herself in the South Park episode “Wing,” which creators Trey Parker and Matt Stone developed after a friend directed them to her website. The exposure reportedly boosted sales of her records. Parker later said Wing sent him a letter thanking him for the increased exposure.
16 George Clooney Barked For Sparky
Actor George Clooney made one of South Park’s earliest celebrity cameos in 1997, voicing Stan Marsh’s gay dog, Sparky, in “Big Gay Al’s Big Gay Boat Ride.” The role contained no spoken dialogue, so Clooney provided every bark, growl, grunt, and yip. The creators gave such a small part to a major Hollywood star simply because they thought the contrast was funny.
17. After Kanye West interrupted American Taylor Swift’s acceptance speech at the MTV Video Music Awards on September 13, 2009, Comedy Central revived a South Park episode mocking his ego. “Fishsticks” portrayed West as too self-important to understand a simple joke and ultimately convinced that he was a “gay fish.” On September 15, Comedy Central aired the episode four consecutive times.
18. American comedian Jerry Seinfeld contacted South Park creators Trey Parker and Matt Stone because he liked the show and wanted to record a guest voice. They offered him the nonspeaking role of “Turkey No. 2” in the 1997 Thanksgiving episode “Starvin’ Marvin.” Seinfeld declined the cameo after receiving the deliberately insignificant part.
19. In 2003, Jennifer Lopez reportedly reacted angrily to her portrayal in South Park’s “Fat Butt and Pancake Head,” which featured Cartman’s hand impersonating her and singing “Taco-Flavored Kisses.” Five months after the episode aired, co-creator Trey Parker said friends working on one of Lopez’s film sets told him that production assistants repeatedly called out, “Ooh tacos, I love tacos,” whenever she passed. According to Parker’s secondhand account, Lopez became so angry that she fired some of those involved, although other workers continued repeating the joke from a distance.
20. The South Park song “Blame Canada” received a Best Original Song nomination at the 72nd Academy Awards, creating controversy because nominees traditionally perform their songs during the broadcast. The FCC prohibited its use of the word “fu*k” on prime-time television, so American comedian Robin Williams performed it while the chorus gasped in place of the profanity. The song ultimately lost to British musician Phil Collins’s “You’ll Be in My Heart” from Tarzan.
15 Most Controversial & Costly Blunders in History
21 China Erased South Park Online
In 2019, South Park released “Band in China,” mocking the Chinese government’s harsh censorship and Hollywood’s attempts to appease it. The episode referenced forbidden subjects, including the Dalai Lama, Winnie-the-Pooh, and organ transplants. Chinese websites subsequently deleted or blocked the show’s pages, videos, forums, and related search terms, effectively banning South Park in China.
22. The “He Who Has No Life” character who terrorizes the South Park children in “Make Love, Not Warcraft” was modeled on a video game project manager named Joey Ray Hall. Hall worked as a senior project manager at Blizzard Entertainment and led its team during the collaboration with South Park. The episode transformed his likeness into Jenkins, the powerful World of Warcraft player whom the children must defeat.
23. South Park creators Trey Parker and Matt Stone found inspiration for “The Book of Mormon” after seeing the Broadway musical “Avenue Q.” In a creative loop, American composer Robert Lopez had co-created “Avenue Q” after drawing inspiration from Parker and Stone’s film “South Park: Bigger, Longer and Uncut.” Their first meeting brought them together for the collaboration that eventually produced “The Book of Mormon.”
24. South Park began with cardboard cutouts inspired by British animator Terry Gilliam’s work for “Monty Python’s Flying Circus.” In 1997, creators Trey Parker and Matt Stone and their small staff spent three months animating the pilot, “Cartman Gets an Anal Probe,” with traditional stop-motion techniques. Later episodes adopted computer animation that preserved the handmade appearance while reducing production to about one week, with some episodes completed in only three to four days. That speed allows the show to parody current events within days of their occurrence.
25. South Park added the on-screen disclaimer “This Is What Scientologists Actually Believe” while depicting Xenu, an alien ruler from Scientology’s confidential teachings, so viewers would not mistake the account for invented satire. The sequence appeared in the November 2005 episode “Trapped in the Closet,” with the message superimposed as a church leader explained the Xenu story.
