onto 1999 Peter's car as he drives to the bachelor party at 1999 Glenn Quagmire's house. 2011 Stewie finds 2011 Brian and the two then attempt to return to the present, but find that the transportation device's batteries (having converted the return pad to take D batteries instead of uranium after their misadventure in Germany) are running low, and move only a bit forward in time to Super Bowl XXXIII. The two manage to take advantage of 1999 Peter dumping his welfare money out of a blimp above the stadium to collect the money needed to purchase new batteries (not before nearly being crushed by 1999 Peter and 1999 Brian's blimp after it is shot down) and start making their way back, but not before briefly landing at 1999 Peter's trial and making the 1999 Kool-Aid Man miss his cue for breaking into the courtroom, causing him to break into pieces.

To Brian's horror, the Civil War has resulted in nuclear attacks across the United States that have caused the deaths of over 17 million people (including Cesar Millan), cutaways have been reduced to Peter flatly declaring "Matthew McConaughey is terrible" against a white background, Cleveland Brown has moved back to Quahog due to Stoolbend being in Confederated Virginia, and Joe Swanson is a cyborg who kills Quagmire — now a mutant humanoid frog named "Frogmire" — for violating curfew. The pair return to 1999 and prevent Brian and Stewie from telling their past selves about the attacks. They return to a present in which 9/11 occurs, but Stewie discovers that Brian instead advised his past self to falsely take credit for the Harry Potter novels. Frustrated that Brian has
