South Park

South Park is an American adult animated sitcom created by Trey Parker and Matt Stone and was developed by Brian Graden for Comedy Central. Since its debut on August 13, 1997, 300 episodes have been broadcast across 26 seasons. It additionally has a theatrical film, South Park: Bigger, Longer, and Uncut, several specials made on Paramount+, and multiple video games.

The series follows the misadventures of four children—Stan Marsh, Kenny McCormick, Eric Cartman, and Kyle Broflovski—and their exploits in and around the titular town in Colorado. The series is famous (or rather, infamous) for its crude toilet humor, profanity, satirical jokes that cover a wide array of controversial topics, and the running gag of Kenny dying. It is also known for its large ensemble cast of recurring characters.

This causes both national and international chaos and fear of what will become of the world, not to mention an impromptu last minute dash for everyone to rush out to their local supermarket and buy out all the cereal and milk. As is standard for every episode of Wacky Races, an unseen commentator provides coverage of who is in the lead and shows a map of their destination, with the twist of having to deliver passengers. Also included, are the logo, the intro, and backgrounds drawn in the classic style.
