NEW YORK — A cartoon family of world-class underachievers is set to burst an enduring TV record.

The Fox network has ordered the 29th and 30th seasons of “The Simpsons,” carrying it through the 2018-19 season. This takes the animated series to 669 episodes, breaking the record for a scripted series set four decades ago with “Gunsmoke,” which produced 635.

Homer Simpson commented: “Take that, ‘Gunsmoke’! You lost a race you didn’t even know you were running!'”

The tale of mythical Springfield and the Simpson clan premiered in 1990 and recently aired its 600th episode.
