Twelve years after South Park hit the airwaves, we are getting a rare opportunity to see the episode that started it all.

For a limited time, SouthParkStudios.com will be streaming the original pilot that launched the iconic Comedy Central series. The entirely handmade episode - it’s amazing what you can do with construction paper! - was hand-animated primarily by Trey Parker and Matt Stone.

The video, which was the basis for “Cartman Gets An Anal Probe,” will contain an additional four minutes of footage not seen in the series premiere.

Every other episode from the comedy’s 13 seasons can already be viewed via South Park’s website.
