'The Daily Show' will be the only program to break into the wall-to-wall showings of the series' 254 installments.

South Park fans are in for a treat as they gear up for the season 21 premiere next month.

On Wednesday, Comedy Central announced an eight-day marathon of the adult cartoon, in which every episode from the past 20 seasons will be shown in order.

Wall-to-wall South Park will begin Sept. 6. The only program that will cut into the marathon is The Daily Show in its usual time slot, according to Comedy Central.

The new season of South Park premieres Sept. 13.

Creators Trey Parker and Matt Stone previously said they will likely go back to the show's previous formula of one-offs after last season got somewhat shaky with one of the main, continuous storylines revolving around an assumed Hillary Clinton presidential victory.

The duo told The Hollywood Reporter before the season 20 premiere that they come up with episode material just days before air, which makes for a stressful office, but allows the show to be one of the freshest on TV week after week.

In addition to the show, Parker and Stone also have a new, highly anticipated South Park role-playing video game coming out this fall.

South Park: The Fractured But Whole, the follow-up to the critically acclaimed Stick of Truth, will be released Oct. 17.
