 * The song "Those Were the Days" parodies the opening theme song of the classic television show All in the Family. Another All in the Family reference is when Homer calls Bart "Meathead" like Archie called Mike in the original series classic.

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 Dr. Pryor 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 Dora (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.
 * At the age of 5, Bart wore the same clothes and shoes as in his current age of 10-year old.
 * There is a goof involving the air conditioner scene, where Rod and Todd are 10 and 8 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 8 and 9.
 * The origin of Bart's catchphrase, "Eat My Shorts," is revealed: Principal Skinner tells Bart to apologize for his impressions, and Bart's response is "Eat my shorts!"
 * This is also the last mention of Snowball I until Season 15.

 * The boy who eats worms was conceived by Al Jean in The Complete Ninth Season's commentary when he used to eat worms as a child and that he looks similar to him.
 * When 5-year-old Bart mooned Principal Skinner, he sang the Batman theme, but changed it to "Buttman."
