All 600 'Simpsons' Episodes to Air Consecutively This Thanksgiving

Record-breaking 13-day marathon concludes with "Treehouse of Horror XXVII"

All 600 episodes of 'The Simpsons' will air consecutively over the course of a 13-day marathon on FXX scheduled to begin on Thanksgiving Day.

The Simpsons broke the record for longest TV marathon two years ago when FXX broadcast all 522 episodes of the animated series consecutively in a 12-day binge. This year, the network will shatter its own record by airing all 600 Simpsons episodes in order, making it a 13-day marathon. 

The epic Simpsons run kicks off noon on Thanksgiving Day through December 6th, Entertainment Weekly reports. The marathon concludes with series' 600th episode, "Treehouse of Horror XXVII," which first premieres on Fox on October 19th. Four episodes from the upcoming Season 28 will air during the 13-day marathon.

After scathing Donald Trump and poking fun at Pokemon Go over the summer, The Simpsons have already offered some spoilers about their upcoming season, including the show's first ever hour-long episode – an all-star hip-hop homage to The Great Gatsby – as well as a plot line that skewers Trump University and Simpson family trips to Boston and Cuba.

Confirmed Season 28 guests include Amy Schumer, Taraji P. Henson, Neil deGrasse Tyson, Suze Orman, Jeopardy! champion Ken Jennings, Seinfeld star Jason Alexander and Keegan-Michael Key.
