Written by Brett Cawley and Robert Maitia and directed by Jansen Yee, it was first broadcast on TBS in the United States on March 28, 2016.
The episode takes place in a previously unseen post-apocalyptic version of Langley Falls that is never seen again, and as such is not considered canon.
[1] The show contains multiple references to popular culture, including a gag sequence being a shot-for-shot remake of a similar scene in Ferris Bueller's Day Off.
In the episode, a tattoo-covered Stan traverses a post apocalyptic Langley Falls in search of his family, while trying to dodge the illusive "Two Hundred", an army consisting of 200 of Roger's personas (and a metaphor for the series reaching two hundred episodes), picking up his neighbor Greg and housemate Roger on the way.
Stan enters his now destructed home, where he finds Principal Lewis with a fire plough in the kitchen.
Flashing forward to the present, Principal Lewis sharpens his teeth and pounces on Stan, attempting to eat him.
Roger joins Stan and Greg's mission to find the family, and the three catch a train in an attempt to avoid a pack of wild dogs.
Francine then shows up and uses the muscle she gained from the trash day experience to help free Stan and then Roger and Greg, and the family all reconcile, but are soon surrounded by all the other survivors of the blast.
Roger flashes back to a moment when he wandered into a "hadron collider" and unintentionally creates 200 clones of himself.
[2] A significant number of recurring voice actors were featured in the episode, including Richard Kind as Al Tuttle, Kevin Michael Richardson as Principal Lewis, and Patrick Stewart as Avery Bullock.
The episode's title and premise are a homage to the post-apocalyptic science fiction series The 100, which aired on The CW.
[3] One of Stan's tattoos is of Santa Claus in a no symbol, this is a callback to the events of American Dad's previous Christmas specials ("For Whom the Sleigh Bell Tolls" and "Minstrel Krampus").
[7] Concluding his review, Kurland said that "As American Dad now boldly heads into the next 200 episodes, with the quality present here, as well as through this twelfth season in general, I can definitively say, Seeya, I would wanna be ya".
