While Family Guy season 23 did rely on two of the show’s oldest jokes in one episode, the long-running series managed to make both of them work thanks to a clever twist. The Simpsons is now the longest-running scripted primetime American TV show in history, with over 780 episodes to its name. However, one of its earliest competitors is quickly catching up. Even before Family Guy season 24 begins, Seth MacFarlane’s darker family sitcom has already aired over 430 episodes since its 1999 debut.
