The Griffins usher in the Millennium with a bang----a nuclear one. Victoria Principal and Patrick Duffy have cameos (as their "Dallas" characters Pam and Bobby Ewing) in a live-action coda to the program, in which every Y2K bug that can bite Quahog (and the rest of the world) does. But the Griffins survive and head off, "Mad Max"-like, on a sardonic odyssey through post-apocalyptic New England, where Griffin's Law prevails---until Peter shoots himself in the foot.

Peter and his neighbors enter a float in Quahog's annual Harvest Festival Parade. They win, but then the trophy turns up missing and the winners all suspect each other of stealing it. Meanwhile, Meg (voice of Lacey Chabert) needs $1100 for a purse, so she takes a waitress job, and takes Stewie with her---pretending that she's an unwed mother and Stewie is her crack baby.
