Lisa's Sax/References

Trivia

 * In addition to revealing Bart's reasons for being a troublemaker and underachiever, this episode is also notable for fueling suspicions of Milhouse's sexuality, after a school psychologist identifies the young Milhouse as having "flamboyantly homosexual tendencies." The episode is also notable for a rare glimpse at Snowball I.
 * This is the last episode in which Doris Grau has a speaking role as Lunchlady Doris (although this episode aired nearly two years after her death). It would also mark the final time the character would speak until Season 18's "The Mook, the Chef, the Wife and Her Homer" (voiced by Tress MacNeille).
 * This was the first of very few episodes Al Jean ever wrote without Mike Reiss.
 * There is a goof involving the air conditioner scene, where Rod and Todd are 8 and 10 during the flashback, the same age they are currently. Bart and Lisa's ages are also goofed as well, since the episode aired in 1997. This would make Lisa age 1 and Bart age 3 because it flashed back to 1990 when 1992 would actually have fit their ages. Maybe this would mean this and all the other episodes of the 3Gxx series were produced between seasons 6 and 7.
 * The origin of the catchphrase 'Eat my shorts' is from when Principal Skinner tells Bart to apologize for his impressions.
 * This is also the last mention of Snowball I until Season 15.
 * This is the only episode that shows the music store King Toot's across the street from Moe's. All others show it next to Moe's, such as in "Lisa's Pony."
 * In the flashbacks Homer had two hairs on his head, but he didn't get two hairs until he found out Marge was pregnant with Maggie.
 * Al Jean, Mike Reiss, Mike Scully, James L. Brooks, Matt Groening all executive produced this episode (and Simpson Tide).

Cultural references

 * While telling Bart and Lisa about 1990, Homer says "the Tracey Ullman was entertaining America with ... crudely-drawn filler material". This is a reference to The Simpsons' debut as "bumpers" airing before and after the show's commercials.
 * Bart's blackboard punishment "I no longer want my MTV" is a reference to the old MTV slogan "I Want My MTV" (and a jab at the channel's declining quality due to lack of music videos and an uptick in non-music related shows, like The Real World).
 * The song "Those Were the Days" parodies the opening credits of the classic television show All in the Family.
 * In the flashback, Dr. Hibbert fashioned his hair and attire like Mr. T in The A-Team.
 * The song Lisa plays on her new saxophone near the end of the episode is "Baker Street" by Gerry Rafferty.
 * A flashback to 1990 shows Homer watching Twin Peaks as Dale Cooper remarks, "That's some damn fine coffee you got here in Twin Peaks... and damn good cherry pie." The Giant is then shown waltzing with a white horse, under a tree with a traffic light hanging from a branch. Homer says: "Brilliant! I have absolutely no idea what's going on."
 * When Lisa's saxophone gets run over, one of the people who runs over it is a man on a tricycle, who promptly falls over. This is a reference to a character played by Arte Johnson, an old man in a raincoat on a tricycle, which is a running gag from the NBC variety show Rowan and Martin's Laugh-In.
 * When little Bart skips along the grass, he bears a resemblance to Charlie Brown sketches.
 * In King Toot's music store, when Homer buys Lisa her first saxophone there is a guitar in the background that is similar to Eddie Van Halen's "Frankenstein" guitar.
 * When Marge, Homer and Lisa visit a preschool recommended by a school psychologist, a child can be seen in the left hand corner of the screen, that appears to be painting Rene Magritte's famous painting "The Son of Man".
