Fans of The Simpsons will really have something to be grateful for this Thanksgiving. ComingSoon.net reports that FXX is airing all 600 episodes of the beloved animated sitcom beginning on November 24, and running for 13 days straight.

The massive TV marathon—appropriately entitled “Every. Simpsons. Ever.”—will run chronologically beginning with the very first episode of The Simpsons, which aired in 1989. Fans who clear their schedules and forgo sleep can spend 300 consecutive hours watching the world of Springfield evolve over the course of 27 seasons. While this certainly isn’t the first time a network has aired a Simpsons marathon (even FXX actually aired a slightly shorter version back in 2014), it's a record-breaking one: Not only will it be the longest Simpsons marathon in TV history, but it will be the longest television marathon ever aired, according to the network.

“The first ‘Every. Simpsons. Ever.’ Marathon was truly so special and landmark in its cultural relevance and impact,” FX Networks President and COO Chuck Saftler said in a statement. “The unprecedented feat of reaching 600 episodes deserves something of that caliber to mark it and celebrate it. Doing this is an act of true fandom, honoring Jim Brooks, Matt Groening, Al Jean, all the writers, artists, directors, people behind the scenes, and the ridiculously talented voice actors who have brought this series to life and kept it at the pinnacle of artistic excellence these past 27-plus seasons.”
