Stan searches for his family after the destruction of the world.
Tropes:
- An Arm and a Leg: Greg loses both of his legs to Lewis trying to satiate his cannibalistic appetite.
- After the End: The episode takes place after a large-hadron collider exploded, wiping out all technology.
- Battle Cry: The 200 shout their names as they charge into battle.
- Big Damn Heroes: Cornered between the Langley Falls cannibals and the 200, the Smiths and Greg are saved by Jeff and a massive, mutated Klaus.Mutated Klaus: DID SOMEBODY ORDER THE FISH?!!
- Decomposite Character: The 200 are revealed to be 200 of Roger's alternate personas manifested into separate individuals as a result of him going inside a hadron collider and bombarded with bosons.
- Earn Your Happy Ending: The Smiths happily reunite and are saved from the other survivors, forming a small commune with Greg.
- Go Mad from the Apocalypse: Played for Laughs. Many of the Smiths' former neighbors in Langley Falls have devolved into cannibals who file their teeth down to points, but Lewis at least is still quite affable with the Smiths while planning to eat them.
- I'm a Humanitarian: Principal Lewis descends into cannibalism, as had many of the Langley Falls survivors.
- Only Sane Man: Aside from the Smiths, Greg's literally the only person in Langley Falls who didn't become a cannibal.
- Real After All: Roger spread rumors about the "200" in order to frighten survivors so that he could steal their stuff. However, it turns out that they are real, and they're all Roger's personas made real by the LHC.
- Spoof Aesop: In the end, Stan tells one his granddaughters that the lesson to be gleamed from the whole adventure is to not let Roger in a hadron collider.Roger: I need to be watched very closely.
- This Is Gonna Suck: When the 200 charge in, Steve confusedly asks if they're on the Smiths' side. Once Stan is hit by a spear from Kevin Ramage, Roger dryly confirms that they are not on their side.
- Unwitting Instigator of Doom: The apocalypse happened because Roger went into a hadron collider to retrieve his sunglasses.
