The Simpsons

The Simpsons is a television series, which airs almost worldwide, and revolves around the eponymous dysfunctional family. It began airing in 1989 and continues to broadcast to today.

The Simpsons, as a show, also exists in the South Park universe, as seen in the episode, "Simpsons Already Did It". At least one of The Simpsons characters exist in South Park as well, as seen in "Cartoon Wars Part II", when Eric Cartman met Bart Simpson. Even though South Park and The Simpsons are competitors, Trey Parker, Matt Stone, and The Simpsons creator Matt Groening have mutual admiration for each other.

"Simpsons Already Did It"
In the Season Six episode, "The Simpsons Already Did It", Butters Stotch, as Professor Chaos, tries to get the town to 'pay' by attempting what he thinks are diabolical schemes, but he finds that all of his ideas were already done on The Simpsons.

Simpsons References to South Park
thumb|300px|right|The Simpsons spoof of South Park. In the Simpsons episode "The Bart of War", Bart Simpson and Milhouse van Houten are seen watching a "brand new episode of South Park". The episode features Stan, Kyle, and Cartman going to a concert, O.J. Simpson attacking and killing the band, and Cartman eventually being decapitated. Marge Simpson sees the boys watching it and turns it off immediately. Kenny did not appear in the parody, which aired during Kenny's permanent death. Also, out of Stan, Kyle, and Cartman, only Stan has a speaking role.

In the Simpsons episode "O Brother, Where Bart Thou?", Bart, Millhouse, Nelson and Ralph stand at a bus stop dressed as Stan, Kyle, Cartman and Kenny. Otto then crashes his bus into Ralph, dressed as Kenny, and says "Oh my God, I killed Kenny!"

The chalkboard gag for the Simpsons episode "The Squirt and the Whale" says: "South Park - We'd stand beside you if we weren't so scared", a reference to the controversy surrounding the episode "201".
