Plot

Chris recounts having to deliver an oral book report on Tom Sawyer, albeit with an erection large enough to keep him trapped in his desk. Ashamed, he prepares to run away, before Brian suggests borrowing Stewie’s time machine to undo the incident. Meanwhile, Joe, Cleveland, and Quagmire decide to buy scratcher tickets and pool their earnings, though Peter decides to buy a horoscope scroll instead. In the past, Brian and Chris swap out present-day Chris for the previous one, saving his reputation, but resulting in present-day Meg’s face being disfigured by a chemical explosion in the science lab. It turns out that the student body’s laughter at Chris’ erection originally distracted Meg from the chemicals enough to spare her from the accident. Peter gets jealous when the others win $123, especially after they show off their purchases. Feeling bad, Stewie, Chris, and Brian travel back in time to stop themselves from interfering. Present-day Chris gives himself an erection by looking up Lauren Boebert and saves the timeline by giving his report. Brian tells Chris that undoing his cringy teen moments is wrong, as such moments are necessary for his development. After stealing some scratchers, Peter gets arrested by the police. When the others bail him out with their remaining winnings, he reveals he was worried that his friends’ earnings made them too good for him, and they apologize for making him feel bad.
