Marge claims she enjoys Parliament but not Funkadelic in reference to the funk collective popular during the 70's. Both individual bands were led by George Clinton. Funkadelic was the heavier among the two individual bands, mixing heavy rock into the funk influence.
The song played during the kissing fantasies of young Marge and Homer is "Happy Together", by The Turtles.
The episode title echoes that of the episode The Way We Was, whitch it self is get's its name from the 1973 film The Way We Were.
Homer's imagined perfect world includes Screaming Yellow Zonkers, Quisp flying by in his spaceship, and the Kool-Aid Man—whom Homer kills by drinking him.
Before meeting the Sea Captain by the docks, Homer says "I guess it's Roe v. Wade, and it's my right to choose." This namechecks the landmark American supreme court decision on abortion.
When the Captain rows Homer across the lake to meet Marge, he sings: "I met her on the mountain, there I took her life. I met her on the mountain, Stabbed her with my knife." These are lyrics from the folk song Tom Dooley, as made famous by The Kingston Trio.
This episode shares the same major storyline as the Who's The Boss? episodes It Happened One Summer I & II, where Tony and Angela discover they shared a kiss while at camp.
In this episode, Milhouse states that his kiss with Homer in the treehouse was his first kiss. However, in the season 3 episode, "Bart's Friend Falls in Love" Milhouse shared his first kiss with Samantha Stanky.
When Homer notices the beer bottle in Bart's treehouse, he cradles it and laments that it "never had a chance be become [his] urine", essentially regretting that he never got to drink it. Seconds earlier, however, Homer had in fact drank the beer when Milhouse poured it out of the treehouse (although he was asleep and was unaware of where the beer came from).
In the Season 19 episode Eternal Moonshine of the Simpson Mind, while traveling through his memories, Homer (literally) destroys the memory of his first kiss in this episode. Bart then makes him believe that Homer's first kiss was with Apu. But this does not count because Frink's machine malfunctioned and Homer now believes it is with Marge again.
