VIDEO: 'South Park' preview and behind-the-scenes documentary

"South Park" returns to the air Wednesday (Oct. 5) after its summer hiatus with its typical offering of off-color comedy and social commentary as told through the eyes of fourth grade boys.

In the episode, Cartman thinks he has Asperger's Syndrome, and he's somehow convinced Kyle and Kenny that it's true. The episode airs at 10 p.m. ET.

In related show news, Comedy Central will air on Sunday (Oct. 9) a documentary about the behind the scenes of the show. "6 Days To Air: The Making Of 'South Park'." This will, no doubt, be an extended version of what Trey Parker and Matt Stone showed on a recent episode of "60 Minutes."

The hour-long special airs at 10 p.m. ET.

Here are preview videos of both...
