- After the End: The Setting.
- All Just a Dream: The whole episode is revealed to be a dream of Pamela Ewing's, parodying Dallas.Pamela Ewing: Oh, Bobby, I just had the weirdest dream. I dreamt I saw the strangest episode of Family Guy, and there was a giant chicken and Stewie was an octopus.
Bobby Ewing: Hey, hey, hey. Come on, now. It's all right. Everything's going to be OK. ...What's Family Guy?
- Dramatic Irony: After being kicked out of New Quahog, Peter apologizes, saying that people apparently didn't need guns, all of them unaware of what's transpiring in the gun-less town behind them.
- Indestructible Edible: Why the family seeks out the Twinkie factory, Peter claiming that they, along with cockroaches, are guaranteed to survive a nuclear holocaust.
- Irony: Lampshaded and discussed by two random guys when Octo-Stewies overrun the town after they get rid of the guns.Random guy: Hey Bob, you remember the other day you were asking me what the definition of irony was and I said-Octo-Stewie latches onto his faceRandom guy: AHHHH!
- Properly Paranoid: After hearing about the Y2K rumor, Peter immediately builds a fallout shelter in the basement and forcibly barricades the family in it. Despite Lois's disbelief, The End of the World as We Know It does happen. Following that, Peter leads the family to Natuck where he believes that a Twinkie factory survived the apocalypse, and turned out to be right again. These instances lead Peter to believe that New Quahog needs guns and so cannibalizes the town's plumbing to fashion them, which unfortunately gets him and the others thrown out of the town. Despite the town's disbelief however, it turns out they do need the guns when Stewie's Weaponized Offspring go on a rampage. Ironically, however, the Griffins are unaware of this and Peter says that he's not always right.
- Weaponized Offspring: The nuclear holocaust mutates Stewie into a half-human-half-octopus creature, who then lays a huge pile of eggs. Next scene, an army of human-octopi march through the town chanting "victory is ours", and attack the people by jumping at them and grabbing their faces with their tentacles.
