Don't settle down for a long winter's nap after Thankgiving dinner is over—turn on your television for what FXX is calling the "longest marathon in TV history." Mashable reports that the network will air all 600 episodes of The Simpsons for 300 hours of Homer and the Springfield gang over the holidays, kicking off on Thanksgiving Day (Nov. 26) and ending Dec. 4. The network did the same thing in 2014, when there were only 552 episodes. The new marathon will begin with the show's Emmy-nominated 1989 Christmas special, per Time. "The unprecedented feat of reaching 600 episodes deserves something of that caliber to mark it and celebrate it," FX Networks President and COO Chuck Saftler says in a statement.
