The last episode of the season alluded to South Park being finished… I just read that South Park is being renewed!
They must have been negotiating their contracts. The creators were screwed by Comedy Central very early on, and when they threatened to leave once, the network gave them some well-earned money. The show has been known before as being a vehicle for the creators to air their issues, and I guess this was another attempt at getting something done.
Thank you, Comedy Central, and I look forward to the new season!
