American Dad! is the criminally underrated sister show to Family Guy. Though both shows have moments of Seth MacFarlane's signature humor, American Dad! does a lot of things better than Family Guy. For one, American Dad! relies more on story-centric and contextual humor rather than the nonsensical cutaways of Family Guy

1 "RAPTURE'S DELIGHT"
All of American Dad!'s Christmas episodes have something about them that makes them great, but "Rapture's Delight" is by far the most ambitious out of all of them, taking what could have been just another average Christmas story and turning it into a post-apocalyptic thriller.

After the rapture occurs, Stan ditches Francine to get raptured himself when he is tricked by a fake Jesus. Francine meets the real Jesus and they begin a relationship. The episode flashes forward years later when the war between Heaven and Hell is raging on Earth. Stan has become a lone warrior. He is recruited by Jesus to find Francine after she is taken by the antichrist, in exchange for being raptured into heaven.

25 Best American Dad Episodes
American Dad just celebrated 250 episodes, so here are the 25 best the show has to offer.
Believe it or not, American Dad had been turning out some of the most cutting edge, consistent animated comedy for over the past decade.

While the Seth MacFarlane vehicle might have been quickly written off in its earlier years, the series has gone on to establish a strong, surreal voice in television and offers some of the strongest stories and characters on the medium. In honor of a whole slew of new episodes beginning to grace TBS for the show’s 15th season, it seemed appropriate to highlight the series’ 25 best entries over the course of its twisted lifespan.
1. Rapture's Delight (Season 5, Episode 9)

American Dad has comfortably fallen into the tradition of their Christmas episodes having some unusual, epic quality. Just like The Simpsons champion their Halloween installments, American Dad has decided to make their annual Christmas episodes appointment television.

Each seasonal greeting from the series is special, but “Rapture’s Delight” might be the only episode of the show that actually made my jaw drop and say aloud, “Holy shit.” This episode really has everything, from turning Bible scripture into a post-apocalyptic Mad Max-esque romp, to bewildering action sequences and a twist ending that still gives me chills when I think about. “Rapture’s Delight” is American Dad at its most untethered and has become the benchmark for not only all other Christmas episodes, but also all episodes of the series, period.
