South Park's creators Trey Parker and Matt Stone jokingly called for their cult sitcom to be cancelled last year, but has its US home taken the writers up on their offer?

After 22 long seasons, the president of US network Comedy Central has now spoken out on the future of South Park – and it looks like we're in for another Simpsons moment.

Kent Alterman explained that any decision to call time on the irreverent series is down to Trey and Matt only, telling TheWrap: "We haven't put an end date on it, and neither has our audience."

Suggesting South Park will continue to age like an old can of Pabst Blue Ribbon, Alterman added: "As long as they're still engaged and interested and bring such vitality to it, we're all game."

It sounds like there are no worries about the series' fondness for controversy either, with the Comedy Central Big Boss praising South Park's contentious storylines for being "sharp and relevant and provocative".
