The Simpsons airs its landmark 500th episode this Sunday -- and its fans are celebrating by setting a world record.
Jeremiah Franco and Carin Shreve broke the Guinness World Record for the longest continuous television viewing by watching all the episodes of the animated Fox comedy, taking them 86 hours and 37 minutes to do so. That translates to more than three and a half days.
It's a telling sign that the series, in its 23rd season, has avid fans. The record was set after Fox invited viewers of the show to partcipate in a challenge that had them watching up to 500 episodes back-to-back.
In a recent issue of The Hollywood Reporter, The Simpsons vets Matt Groening, Al Jean, cast members Dan Castellaneta, Hank Azariaand alums like Conan O'Brien discussed the show's significance.
