Think Netflix binge-watching is extreme? D’Oh! Just wait for the most epic of TV marathons—all 25 seasons and 552 episodes of The Simpsons in chronological order!

Running 24 hours a day from Aug. 21 through Sept. 1, FXX is gifting fans with the mega marathon from the long-running animated series plus the 2007 movie. 

At the same time, FXX will also be launching Simpsons World—described as “the ultimate Simpsons digital experience”—in October. After the marathon wraps in early September, FXX will continue to schedule episodes across their weekday and weekend lineup, airing mini eight-episode marathons every Sunday starting at 4 p.m. ET. 

The Simpsons was created in 1989 by Matt Groening, and has gone on to win 28 Emmy Awards. The marathon kicks off Thursday, Aug. 21 at 10 p.m. ET on FXX.
