Mrs. Krabappel falls in love with someone ("Woodrow"/Principal Skinner). Ironically, Mrs. Krabappel tells Bart on "Bart the Lover" that she would never date Seymour because "...his mommy won't let him out to play".
Bart's Inner Child: Kids getting sick/injured in a backyard (the kids hurting themselves on the trampoline/the kids getting food poisoning from oysters at Martin's party)
A Simpson male (Homer/Bart) gets involved with Principal Skinner's love life (accidentally sets Skinner up with Patty instead of Selma/helps keeps Skinner's relationship with Mrs. Krabappel a secret).
Principal Charming and Bart the Genius: Bart has a large permanent record of all his misbehavior and poor academic skills.
The Springfield kids (and Bart and Lisa) are at a lame party.
Homer Alone: Homer speaks to a family member through a bullhorn (tries to talk to Marge after she snaps and blocks traffic/tries to ask Bart where the TV remote is during the stand-off).
A Milhouse Divided and Lisa the Vegetarian: An episode ends with a character change (Milhouse's parents stay divorced [at least until the later episodes]/Lisa is still a vegetarian [though some episodes do depict her eating meat, most fans write that off as either "The episode was written before that happened" or "Lisa's eating a meat substitute"]/Skinner and Krabappel continue dating [even though they broke up on "My Big Fat Geek Wedding"]).
Lisa the Vegetarian: The Simpsons have a riding lawn mower
Radio Bart: Bart tricks the town's news media into thinking something happened (Timmy O'Toole getting trapped in a well/an octopus on top of the school).
Treehouse of Horror IV ("Nightmare at 5 1/2 Feet") and Bart After Dark: Principal Skinner's mom doesn't approve of him talking to or being around women that aren't her (took away Skinner's car keys for talking to a woman on the phone, which is why he's riding the school bus/is offended over Skinner being one of the many Springfieldianites who visited The Maison Derriere/spies on Skinner and Krabappel during Martin's birthday party).
Goofs[]
Edna's name misspelled as "Enda"
Mrs. Krabappel's name on the envelope is misspelled as "Enda" when Bart is opening and reading the letter, but is spelled correctly when viewed in closeup.
Nelson kept rejecting Martin’s invitation to his birthday party, but he still attended. He was likely bored that weekend, as was the case with Bart and Milhouse, or he may have intended to beat up Martin or some other nerd there.
Lenny with a yellow beard
When Maude Flanders accuses Skinner and Krabappel in engaging in a sexual relationship, Lenny's beard is colored yellow.
After Skinner announces that he is a virgin, Homer and Marge change positions with other when the camera switches from a long-distance shot to a close-up.
When Principal Skinner puts his mortarboard on, the tassel is hanging on his right-hand side (i.e. the viewer's left). It should be hanging over his left-hand side, as tassels on the right indicate that the wearer has not yet graduated from their course.
Cultural References[]
The Mathemagician, whom Martin hires for his party, is modeled after Bill Gates. Gates himself would later appear in the B-plot of "Das Bus".
Bart saying "Set your faces to stunned" is a reference to the Star Trek catchphrase "Set your phasers to stun".
After Chief Wiggum said "Those are hot dogs, Armour hot dogs," Superintendent Chalmers responded "What kind of man wears Armour hot dogs?" This is a reference to the ad campaign song by Armour hot dogs[1], which also once appeared in the episode Lady Bouvier's Lover.
