Take a sneak peek at the trailer for a documentary on the making of South Park.

What started off as a show featuring farts, swearing and other rude things is now a massive hit show.

But that doesn’t mean the creators have grown any more mature or have changed their ‘fly by the seat of their pants’ attitude toward making the show.

As much as a lot of South Park stuff is pretty much revolting to me, I am really interested in seeing this. Especially when it comes to a show that has no qualms about pushing every single button they can.
