When The Simpsons celebrated Fox’s 25th anniversary Sunday night by taking a swipe at Fox News, it was only the latest example of what has become a long tradition. Indeed, taking shots at Fox seems to be The Simpsons’ favorite way of celebrating all its milestones. For the show’s 20th anniversary episode, a Springfield billboard during the opening credits read “Fox Network: Still Sucking After 20 Years.” For their 400th episode, The Simpsons did a riff on media censorship, ending with the 400th episode itself getting censored.
