In Bart's fantasy about the snowy July 4, Benjamin Franklin's sled says "Don't Sled on Me", a play on the famous serpent flag "Don't Tread on Me".
Despite passing the fourth grade, Bart, of course, remains in Mrs. Krabappel's class in all subsequent episodes, since virtually no time ever really passes on the show.
During the episode, Bart writes "I will not fake my way through life" on the chalkboard. This is the first episode to use an opening sequence gag within the actual episode, and the first chalkboard gag to be used within an episode itself.
The idea behind the grade on the refrigerator would reappear in Bart's Nightmare where a letter grade would appear and the mood of the Simpson family would differ, with a scene similar to the last scene in this episode.
Milhouse's voice seems to be deeper in this episode.
This is the third episode with Bart's name somewhere in the title.
This is the first episode to use the Season 2-early Season 20opening sequence. However, in this particular episode, the colors are in completely different hues of bright and dark (like how Bart's shirt is salmon-colored in the actual episode). This is because this is an early prototype of the Season 2-early Season 20 opening, and this is the only Season 2 episode to have the different bright and dark hues in it before the colors were changed to their correct hues for the rest of Season 2 and throughout the series until Season 20's "Lisa the Drama Queen".
The sailboat painting that is above the Simpsons' couch makes its debut appearance.
While the citizens stand in a circle and hold hands singing during the snow day scene, Sideshow Bob is seen in handcuffs, referencing "Krusty Gets Busted", which was two episodes earlier.
Bart's shirt appears to be a salmon pink color in this episode rather than the normal orange. This may be due to the episode showing an early prototype of many of the hues and colors, like how the opening was in the same episode.
The exterior shot of Springfield Elementary School at the beginning of the episode was later reused in several episodes from Seasons 2 to Seasons 12/13, thus making this particular shot the first recycled animation to be used in the series.
This was, and still is, the episode with the highest ratings in the show's history, pulling around 33 million viewers when it made its debut.
When the episode first aired in 1990, it performed so well that it had more viewers than The Cosby Show, which aired at the same time on NBC.
Treasure Island: Bart tries to fake his way through an oral report about the book, but struggles when asked the name of the pirate.
McGraw-Hill: Treasure Island is published by them, and were mentioned by Bart while peppering his poorly-prepared oral report.
The Old Man and the Sea: Martin reads it and recounts to the class in a first person narrative in his oral report. However, Martin wears an Ernest Hemingway costume, who is the author of the book. The protagonist of The Old Man and the Sea was an elderly man named Santiago.
The Declaration of Independence: Bart has to do homework on it, and imagines that the Founding Fathers ignored the declaration, and instead played out in the snow.
King Kong: The 'gorilla film' is a spoof, although the gorilla film shows Gorilla the Conqueror's final fate imprisoned in a cage and set adrift on the high seas, whereas King Kong fell to his death from the Empire State Building after being shot by fighter planes.
During the Snow Day sequence when Patty and Selma are on a horse-drawn sleigh is a reference to the lithograph The Road- Winter by Otto Knirsch, which was used as a christmas card by Currier and Ives throughout the 19th and early 20th century.
In this episode and the next Bart's shirt is almost tan colored instead of orange
