The Simpsons is a very well-known television series that revolves around the eponymous dysfunctional family. It first aired on 1989 and continues to broadcast new seasons today with well over 700 episodes in total.
This show also exists in the South Park universe, specifically in the episode "The Simpsons Already Did It". At least one of The Simpsons characters, Bart Simpson, exists in South Park; Eric Cartman meets him in "Cartoon Wars Part II". Trey Parker, Matt Stone, and The Simpsons creator Matt Groening have mutual admiration for each other.
A driver shouts "Hey, Mackey! Now we see what you and Homer Simpson have in common, d'oh-pe! Ha ha ha ha!" at Mr. Mackey, a reference to Homer's catchphrase on the show. He even mentions Homer by name.
In the Season Six episode "The Simpsons Already Did It", Butters Stotch, as Professor Chaos, schemes to put South Park in chaos. Dougie reminds him that his ideas are unoriginal because they were already done on The Simpsons:
- Butters wants to block out the Sun, as seen in "Who Shot Mr. Burns? (Part One)".
- Butters cuts the head off of a statue, as seen in "The Telltale Head".
- Butters plans to sell a monorail to the town and then leave with all of their money, as seen in "Marge vs. the Monorail".
- Butters plans to start a website that spreads rumors about the townspeople, as seen in "The Computer Wore Menace Shoes".
- Butters plans to bury a winged skeleton wanting people to believe that it is an angel, as seen in "Lisa the Skeptic".
- Butters wants to bring the World Cup to town to incite a soccer riot, as seen in "The Cartridge Family".
- Butters wants to shake up beer cans with electronic paint mixers, as seen in "So It's Come to This: A Simpsons Clip Show".
The main plot of this episode has Cartman grow a race of Sea Creatures that evolve and worship him as their creator. This is a drawback to the "The Genesis Tub" skit of "Treehouse of Horror VII", where Lisa accidentally grows a civilization from her lost tooth.
By the end of the episode, Butters goes insane and hallucinates the townspeople and geography of South Park as they would look on the Simpsons. The South Park characters and their The Simpsons counterparts are listed below:
- Dougie as Bart Simpson

In "Cartoon Wars Part II", Cartman meets one of the main characters of The Simpsons, Bart Simpson, who shares his hatred of Family Guy. The pair work together to cancel Family Guy. Bart's opinion later changes after Kyle gives him one of his "gay little speeches".

Simpsons References to South Park
In the Simpsons episode "The Bart of War", Bart and Milhouse watch a "brand new episode of South Park". The episode features Stan, Kyle, and Cartman in concert. There O.J. Simpson attacks and murders the band members. Cartman eventually gets decapitated. Marge Simpson finds the show too violent and turns off the TV. Kenny is absent from this parody, likely due to his permanent death in South Park. Only Stan, out of him, Kyle and Cartman, has a speaking role.
Coincidentally, due to the blending of the two shows' animation styles, the boys appear similarly in this parody as in "The Simpsons Already Did It" except for their usual beige skin color.
In The Simpsons episode "O Brother, Where Bart Thou?", Bart, Milhouse, Nelson, and Ralph stand at a bus stop respectively dressed up as Stan, Kyle, Cartman, and Kenny. Otto crashes his bus into Ralph and exclaims, "Oh my God, I killed Kenny!".
The chalkboard gag on The Simpsons episode "The Squirt and the Whale" is: "South Park - We'd stand beside you if we weren't so scared". It references the Muhammad controversy from the South Park episode "201". After "Cartoon Wars Part I" aired, The Simpsons writers sent Parker and Stone flowers to thank them.
"Treehouse of Horror XXV" - A version of the Simpsons family in South Park-style animation appears at the end of the episode; with Bart wearing Stan's hat, Lisa wearing Kyle's hat and Maggie Simpson looking like the South Park-version of a Canadian, similarly to Ike.
"The Cad and the Hat" - In the couch gag for this episode, Homer notices that the portrait of the sail boat on the wall is missing and Bart accuses another animated series of stealing it. As a result, Homer travels into the South Park universe (which he describes as a "third grade diorama") and parodies of The Boys appear, Homer asks them if they stole his portrait, to which they respond by cussing at him.
- Nancy Cartwright was at one point approached to star in South Park, but rejected the offer.
- Some fans refer to Hans Moleman as The Simpsons version of Kenny McCormick since they both get killed in many episodes.
- The Simpsons are based on Matt Groening’s family just like Kyle and Stan’s family which are based on Matt Stone and Trey Parker.
