When Lisa is talking to Mr. Burns at 18:12 minutes, her teeth turn blue on the left, and red on the right.
When Homer is eating his sandwich 14:49 minutes in his mouth he is beardless but when it zooms out he does have a beard.
Homer arrives at work at 3:00pm (fashionably late?), but when he falls asleep and then wakes up he realizes it is 9:30PM, to which he phones Marge and claims "those 12-hour days are killing me!" Homer says at the beginning of the episode that someone punches in for him.
Burns drinks from 5:05 pm until 8:30 pm, but passes Homer at 9:30, meaning he stumbled drunkenly around the plant for a solid hour. Neither Homer nor Mr. Burns notice (or respectively choose to ignore) each others shortcomings, in this case Homer's sleeping on the job and Burns' drinking on the job, as Burns accuses Homer of working late, which Homer does not say anything else and accepts the compliment "You and I are a dying breed." The chance meeting has Burns believe Homer is a hard-working employee who can be trusted, hence the unraveling of the episode.
When Burns starts drinking, the glass disappears for a frame.
At the end of this episode, Burns' campaign for governor presumably ends in his defeat, yet the issue of the government threatening to shut down the Power Plant due to its numerous safety violations remains unresolved, and actually becomes a running gag in future episodes.
Continuity
At the retirement home, after Burns' election commercial, the Duff Beer commercial from "Homer's Odyssey" can be heard.
Bart's scrapbook contains a clipping headlined "Vandal Decapitates Town Statue... Who is El Barto?", referencing his own exploits in "The Telltale Head".
The chalkboard gag implies Bart photocopied his buttocks which he later did in Special Edna.
Trivia
98% of Springfield voters see Mr. Burns as despicable or worse.
This is the first episode to be rated TV-14.
Mr. Burns's argument that the fish is a product of natural selection is validated by himself spitting the fish out. Tasty fish are more likely to be eaten by predators than bitter tasting fish. However by claiming during the campaign that the three-eyed fish would have "a taste that can't be beat" he caused his own political downfall.
