Aluminum Christmas Trees: The "thin stew" that Principle Skinner reminisces about living on in Vietnam as a prisoner of war is a reference to a real Vietnamese dish called a Thai Tom Kha Goong.
Crosses the Line Twice: A drugged up Burns murdering Moleman with a power drill to the skull? Horrifying. Him hallucinating Moleman as the Lucky Charms leprechaun, along with Moleman's monotone reaction of "Oh no, my brains" makes it dark comedy gold.
Hilarious in Hindsight: Superintendent Chalmers wonders what Agnes Skinner under the influence of a mind-altering tye-dyed dress would be like. Fast-forward three episodes in "Bart The Fink", and they're dating. What exactly happened in that park? Or was the two of them dating an isolated incident that had nothing to do with what happened at the park?
Squick: Mr. Burns losing a nail in Homer's beer. And his remark on it only makes it worse.
Mr. Burns: Whoops. Lost a nail. Well, that's leprosy for you.
Values Dissonance: Springfield Elementary institutes school uniforms, which are shown to be soul-crushing and reduce the kids to listless and depressed zombies in a matter of days. This will come off as somewhat humorous in a puzzling way in most countries outside of North America and Western Europe where school uniforms are required and the kids' personalities don't suffer much from it.
