Trivia: This is the last episode to feature the voice of Phil Hartman, aired September 27, 1998. In it, he voices Troy McClure in a nature video about birds. Phil had been killed by his wife in a murder-suicide that May, and Troy McClure and Lionel Hutz were never replaced.
Trivia: When Homer says to Lisa "How could they change my character from cool to stupid?" and Lisa replies "creators love to tinker with shows, they drop characters, change some and push others into the background", in the background walking past the window you can see Mr. Largo and The Capitol City Goofball: two long since backgrounded characters.
Trivia: At the end of the episode, when Uptown Girl has finished playing, you can hear Homer mutter under the song, 'I buried Flanders'. This is a Beatles reference as in one song John Lennon sang Cranberry Sauce and many fans misconstrued it as 'I buried Paul', as there was a rumour at the time that Paul McCartney was dead and had been replaced by a look-a-like. It's a very slick reference.
Trivia: During the flight to Japan, Marge reminds Homer that he had seen the Japanese movie "Rashomon" and had liked it, to which he responds something like "I don't remember it like that". This is a reference to that very movie, in which a number of people witnessed a murder and each gave a very different version of the events after what each "remembered".
Trivia: Another thing "The Simpsons" predicted: Towards the end of this episode, a sign outside of a film studio shows the 20th Century Fox logo with "A Division of Walt Disney Co" written under it. Nineteen years after this episode aired, Disney purchased many assets from 20th/21st Century Fox, including "The Simpsons."
