- Genius Bonus: "Vitamin R," which "malk" proudly claims it is full of, is a slang name for Ritalin.
- Hilarious in Hindsight
- Bart discovers that for years, he's actually been drinking "Malk" instead of milk. Malk now actually exists. It's almond milk.
- The malk gag may also now bring to mind the name of a hit song by Chevelle, "Vitamin R (Leading Us Along)" (though that song is refereeing to the afore-mentioned Genius Bonus).
- In the very next scene, a gag about Springfield Elementary carrying books banned by other schools includes, among other books, Dr. Seuss's Hop on Pop. While nothing more than a throwaway Arson, Murder, and Jaywalking joke when written, there was actually an (unsuccessful) attempt to ban it from the Toronto Public Library in real life years later.
- Edna and Skinner hate each others' guts in this episode, which is amusing considering the two hooked up only two seasons later.
- The Civil War reenactment park raises it's prices after being bought out by a cooperation called "Dizz-Nee." 20+ years later, Fox, the company which owns The Simpsons', was bought out by Disney.
- Memetic Mutation:
- Spawning a meme? That's a paddlin'...
- Purple monkey dishwasher
- "Is that gum? Is that gum? Is that gum?"
- Moral Event Horizon: The reenactment soldiers cross the line by chasing after a whole classroom with the intent of murder for "trying to learn for free", ending in them lynching Uter when he can't catch up to the school bus. And Skinner crosses this line (at least in the eyes of some) by showing no emotion to Uter's fate, just admitting that permission slips will keep the boy's parents from suing him. The Season 7 episode "Much Apu About Nothing", where Skinner attacks Uter for being German, only made this even worse.
