Interesting Interview with Trey Parker

In all fairness, few shows exceed the ten-year mark without getting stale. What makes "South Park" any different?

"The fact that we still write and direct and voice every show ourselves, it's really more like a band," Parker said. "Because it's basically watching where we are now compared to where we were five years ago. It's sort of us growing up with the show, and the show growing up with us -- or growing down."

"We always said, When we feel like we don't want to write the show anymore, ourselves, then it's time to end the show," he said.
