If you happen to be a devout fan of The Simpsons, FXX has made your day.

To celebrate the FX-branded network's recent deal to air reruns of the long-running comedy, FXX will air every single episode of the series in a 12-day, 24-hour marathon beginning on Aug. 21 and concluding on Labor Day (Sept. 1).

As part of the company's FXNow streaming service, the show's full catalog will soon be made available for online streaming on a new site called "Simpsons World."

Although a release date for the site is not set, FX Networks CEO John Landgraf said Monday that he expects it to be in October, speaking to reporters at the Television Critics Association summer press tour.

The Simpsons, which is the longest-running American primetime series, begins its 26th season this fall on Fox.
