In an appearance on Jimmy Kimmel Live! on Monday, South Park creators and showrunners Trey Parker and Matt Stone produced the prosthetic they used to deepfake Donald Trump’s penis in the season 27 premiere last year and managed to get the host — a longtime foe of the president — to wear it on his pinky finger.
Parker and Stone made a good amount of news in their rare television appearance, revealing that season 29 of South Park will premiere on Sept. 16 on Comedy Central. And, discussing the 15th anniversary celebration of The Book of Mormon, Parker said he would be playing Joseph Smith on Broadway with Stone also taking the stage.
Parker and Stone are coming off a two-season run of South Park that ended in December and became a cultural milestone as they mercilessly spoofed the Trump administration, creating a ratings bonanza, angering the White House and reinvigorating the show. And, somehow, they got away with it, penis jokes and all.
“We hide behind cartoons, Parker joked at the top of the segment.
The duo made such a splash with these 12 perfectly timed, written-on-the-fly episodes, they received a nomination at the Producers Guild of America Awards for the 12-episode seasons 27–28 run, an honor not yet given to an animated series. Despite all of the newsmaking on Monday from the South Park creators, it was the penis prosthetic that was the real star of the segment.
“In that season of South Park, we did a deepfake of the president,” Parker reminded Kimmel. “We actually brought our deepfake AI rig to show you how we did Donald Trump’s wiener on the show — very sophisticated technology. This was actually it right here. This is how we did an actual foreskin. And so for the show, we just put it on like this.”
Kimmel responded, “If [Trump] doesn’t burn down the Smithsonian, I hope that winds up there one day.”
Toward the end of the segment, Parker encouraged the host to handle the prosthetic. Kimmel, who has sparred with Trump for years, was quick to oblige and placed it on his pinky finger.
“It does feel good,” Kimmel said, before speaking to it. “Hello, little fella. Why are you making so much trouble? It’s OK you don’t even work anymore.”
Parker and Stone also revealed that the inspiration for Vice President J.D. Vance’s persona on the latest South Park seasons was Tattoo from the ’70s hit TV show Fantasy Island, portrayed by Hervé Villechaize, who was born with dwarfism and had a distinct French-accented voice.
“It was just gonna be a one-off joke about Mar-a-Lago being kind of like Fantasy Island, and we were like, ‘Oh yeah, we should have him be Tattoo.’ It was gonna be one shot, and we all just loved it so much. We loved him as a little character. We think that’s good for another 27 years,” Stone said.
In addition to all of the South Park chat, Parker and Stone caught Kimmel and the audience up on their other big projects. In 2021, Parker and Stone purchased Casa Bonita, a massive 52,000-square-foot venue and Mexican restaurant in Lakewood, Colorado, out of bankruptcy and put $40 million into a large-scale renovation and retooled menu. In 2024, they released a feature-length documentary, ¡Casa Bonita Mi Amor!, about the major undertaking.
“We thought it was gonna be around $7-8 million and the renovation would be like $50 [million], but it is going really well, and we think we might make our money back sometime around 2040,” Stone joked.
Parker added that they have been able to bring some of the magic back to the restaurant the two loved as kids growing up in Colorado. A 2003 episode of South Park — in which Cartman misleads Butters into going missing so he can score an invite to Kyle’s party at the kid-friendly Mexican-themed venue — is named for the restaurant.
“In the ’70s, when we were kids, it actually had puppet shows and magic shows, and it had really gone downhill,” Parker recalled. “By the time we were in college, it was kind of a joke, but you’d still bring people and go, ‘Look how dumb this is.’ We just tried to bring it back to what it was. It’s very cool, but we can’t go now because we don’t have time. It’s in Denver.”
The Book of Mormon, Broadway’s long-running smash hit, was also a hot topic on Kimmel on Monday, as Parker and Stone celebrate its 15-year run. On May 4, a three-alarm fire broke out at the Eugene O’Neill Theatre in its electrical and spotlight room, causing performances to be canceled for two weeks. The show is set to reopen on Thursday, and some surprises are in store next month as original cast members return for select performances and Parker and Stone are set to make cameos in the production.
“We’re doing the 15th anniversary, and a lot of the original cast is coming back and doing it for a week,” Parker said. “And we’re actually going to play some of the parts. I’m gonna play Joseph Smith. I finally get to be on Broadway, which is just something I had to do.”
While Stone wasn’t sure what role he’d play, he added, “The fact that I’m going to be on Broadway is hilarious, because I can’t dance and I can’t sing and I’m not funny, and so I’m just gonna get up and do a thing. I’ll be able to say I was on Broadway.”
“Magical Mormon Mystery Week,” running June 9–14, will feature original cast members Josh Gad and Andrew Rannells, plus Parker and Stone and more special guests.
