The complete and until today unaired pilot of South Park for Comedy Central, with an additional creator's commentary track. About 90% was recut into the first episode, "Cartman Gets an Anal Probe," but with a few slightly altered scenes and characters. After gaining underground popularity with two shorts that you've all probably seen already at this point, Trey Parker and Matt Stone were contracted by Comedy Central to produce a full pilot episode for a potential show based on the shorts. This pilot episode is what would ultimately lead to a series that is now 12 years old, spans over 180 episodes, and is one of the most successful shows in the history of cable television both in ratings and revenue. The pilot is also the only episode in the series that, like the original shorts, uses stop-motion animation of paper cutouts instead of computer software.
