A single show will take over a network for eight days leading up to its season 21 premiere. The show is “South Park,” which will be the focus of a marathon on Comedy Central starting Wednesday, Sept. 6.

The show will run 254 episodes — 127 hours — “wall to wall” leading up to the season premiere on Wednesday, Sept. 13, Comedy Central announced.

“With the exception of ‘The Daily Show with Trevor Noah’ airing during its regularly scheduled time, it will be wall-to-wall ‘South Park’ for eight historic days,” Comedy Central said. “In celebration of the 21st season, Comedy Central is also launching a special ‘South Park’ emoji that will be featured on Twitter whenever a user tweets any of the following hashtags: #SouthPark, #NewSouthPark, #SouthParkPremiere, #SouthPark21, #Memberberries, and #Cartman. The emoji will go live on Wednesday, September 13 and be active throughout the entire season.”

Co-created by Trey Parker and Matt Stone, “South Park” launched on Comedy Central on Aug. 13, 1997, and became one of the cable network’s signature shows. The series airs Wednesdays at 10 p.m. ET/PT.
