"Mountain of Madness": People trapped in a snowed-in building, insanity from trying to escape a snowed-in building, and someone trying to tunnel out of a snowed-in building.
"Lisa the Simpson": Lisa reads a made-up word ("dumbening"/"know-it-all-ism") and declares that it's not a word.
"Home Sweet Homediddly-Dum-Doodily": Someone is put inside a sack (Bart is put in an onion sack after his lice-ridden clothes are burned/Skinner is put in a dodgeball sack as part of the school's revolution against him).
"Homer Goes to College": Bart and Lisa miss an Itchy and Scratchy episode where something finally happens (Scratchy finally kills Itchy/Itchy and Scratchy finally kiss).
Bart Gets an "F": Bart is summarized as being an "underachiever and proud of it," and reference to a man "writing his name in the snow."
"Bart on the Road": Someone foolishly believes that cruise control drives a car for you.
There are two indirect male genitalia references in this episode. The first was when Groundskeeper Willie said "That's the last time you slap yer Willie around!". The second was when Skinner said "You did it Nibbles! Now chew through my ballsack!".
The couch gag (sort of) continues into the episode, when Homer is finished watching football. The couch gag is based on football.
Why would Ned say the song Feel Like Making Love is great when he is against sex?. (This is unless he was just saying that to be nice to Homer)
Bart burns the book Johnny Tremaine, but on the episode "Whacking Day," he read the entire book and liked it.
Skinner's line while Bart is burning books is, "Not Huck Finn! I spent hours crossing out the sass-back!", but in the closed captioning, it reads, "Oh, now you're just burning innocent linoleum. What did it ever do to you?".
When the children are in flour sacks as they go to sleep, Bart rests his head on his red jacket. When Skinner switches the light off, it turns gray.
If the schools in Springfield are being suspended because of bad weather, why is the Elementary School the only one to not be suspended? Plus if the middle and high school were cancelled, all of the schools of the district should be closed, because that's how a school district works.
When Skinner was trying to call the kids' parents, the telephone hook was gray, but when he turns it off, the hook turns to blue.
Lisa is not present in most of the school scenes, such as in the cafeteria or when the kids rebel against Skinner. She reappears when the kids are going to sleep. It is unlikely that she left the room since Skinner locked the doors.
Nibbles' hamster-ball crashed through Ned's' car windscreen, but when the vehicle hit the salt silo, it was intact.
