(Los Angeles, CA) -- 'The Simpsons' is reaching another major milestone and showing no signs of stopping just yet. The 700th episode of the animated comedy series aired on Sunday. It's was a flashback episode called "Manger Things." Ahead of the episode, the show's creator Matt Groening told USA Today he's proud of the Apu despite the controversy. The character came under fire because although he's a Indian character, he was voiced by a white man until recently. Fox recently renewed the show for two more seasons, which will push it to 757 episodes spanning 34 seasons. Executive producer Al Jean says he's not sure how much further the show will go beyond that. However, he says he's confident it won't end even after he's gone.
