YMMV / Family Guy S 4 E 1 North By North Quahog

• Harsher in Hindsight: At one point when Chris and Meg are fighting, Brian makes a comment that the stress of putting up with them would make him shoot himself. Five years later and it turns out that he wasn't exaggerating.
• Hilarious in Hindsight: Peter and Lois find a fictional sequel to The Passion of the Christ in Mel Gibson's home. In June 2016, it was announced that Mel Gibson would be making a sequel which is planned for a 2025 release.
• Memetic Mutation:
  • The scene of Stewie slowly giving Brian a look of disbelief after a Freudian Slip has become a popular reaction image.
  • The scene of Peter running away from the biplane has become the basis for the "Don't Do X, Worst Mistake of my Life" meme, with what Peter is running from being changed to various things.
