<P> South Park is an American adult animated sitcom created by Trey Parker and Matt Stone who also do the majority of the voices . Both Parker and Stone do most of the male characters on the show along with April Stewart and Mona Marshall, who do the female characters on the show . Guest stars have lend their voices to the show including Jay Leno, George Clooney, Robert Smith and the comedy duo Cheech & Chong voiced characters representing their likenesses for the season four (2000) episode "Cherokee Hair Tampons", which was the duo's first collaborative effort in 20 years . </P> <P> Characters in the show, according to Parker and Stone, are inspired by people they met when they were kids . Stan Marsh is made based on Parker himself while Kyle Broflovski is based on Stone himself . Eric Cartman is partially named after and based on Matt Karpman, a high school classmate of Parker who remains a friend of both Parker and Stone . Cartman is also inspired by All in the Family patriarch Archie Bunker, of whom Parker and Stone are fans . They state that creating Cartman as a "little eight - year - old fat kid" made it easier for the two to portray a Bunker - like character after the introduction of political correctness to late - 20th century television . Kenny McCormick was based on the creator's observation that most groups of childhood friends in small middle - class towns always included "the one poor kid" and decided to portray Kenny in this light . Butters Stotch is loosely based on South Park co-producer Eric Stough . </P>
