Celebrate 15 years of American Dad! with this exclusive preview of the show's Top 15 episodes

In honor of the 15th anniversary of American Dad!, one of the most beloved animated sitcoms of all time that prominently features both a pansexual alien and an ex-Olympic skier who is now a talking fish (it has some tough competition in that category), TBS is airing a handful of celebratory marathons this week—specifically curated collections of episodes tailored to specific characters and a countdown of the show’s top 15 episodes as chosen by the series’ creators. For a show that’s been on a for a decade and a half, this all seems like a cleverly designed way to lure in new viewers who may have initially written off the show as a Family Guy knock-off with a more political bent. It’s so much more than that now, with episodes dedicated to fighting the Antichrist, escaping a Twilight Zone-esque TV demon, and uncovering the dark secrets of a madman named… Ricky Spanish.
