Cartman, Kenny, Kyle & Stan have to be the longest serving students ever! It looks like they are not graduating anytime soon though, as Comedy Central has renewed South Park for 2 more seasons. This will bring it up to it’s 17th season.
Trey Parker and Matt Stone created this, sometime, controversial show back in 1997. Not only have they created more than 200 shows but there has also been a spin off film, South Park – Bigger, Longer and Uncut. This took in $83million at the worldwide box office and was even nominated for an Oscar in the Best Original Song category (Blame Canada).
