- Fanon Discontinuity: The episode depicts the lives of The Simpsons throughout the 90s, completely ignoring that the events of episodes which aired during the show's earlier seasons that took place in the 90s, and completely rewriting canon as a result. This may have been upgraded to Canon Discontinuity in later seasons, since they continue to depict Homer and Marge as having gotten together in the mid-1970s. More charitable fans view the episode as "What if Homer and Marge first met in the 90's?" rather than replacing their well-established love story.
- Hilarious in Hindsight:
- While splitting up their possessions, Homer takes all the stuff that will be considered worthless in the late 90s-2000s (vinyl LPs, Enron stock, a typewriter) and gives Marge all the stuff that will be successful later on (CDs, Microsoft stock, a computer). However, in The New '10s vinyl LPs saw a resurgence in popularity thanks to the analog audio provided by vinyl being considered the best listening experience for music while CDs were rendered obsolete thanks to the aforementioned resurgence as well as the rise of MP3 files and digital streaming. So to modern viewers, it appears Homer actually won that specific split.
- The name of the episode is an obvious Shout-Out to That '70s Show. In 2021, Netflix ordered a spinoff of that series that was indeed named That '90s Show.
- They Changed It, Now It Sucks!: The general response to Homer and Marge dating in the 90's rather than in the 70's.
