Lisa barely appears in this episode, and Maggie doesn't appear at all. However, Maggie does appear in a deleted scene.
The deleted scene also makes a reference to the episode "Marge gets a job".
Werner Klemperer who voices Colonel Klink in this episode did not use Klink's real voice. He instead used the director's imitation of Klink, as he forgot how Klink talked after Hogan's Heroes was cancelled.
The duck who works at the nuclear power plant is named Stewart.
"Mandy": The song Homer sings about Mindy and Marge at the end is to the tune of this song.
"Big Apple": Capital City is named the "Windy Apple" a reference to New York City's nickname the "Big Apple" and Chicago's nickname the "Windy City."
"The Wizard of Oz": Mr Burns keeps a number of the winged monkeys in a cage, to unleash on people who charge room service to the company. When Homer and Mindy do so, Burns sends them off to attack with the infamous line "Fly, my pretties! Fly!" Unfortunately, because the monkeys can't actually fly, they all plummet to their deaths. Burns groans at this, then tells Smithers to "continue the research."
There is a lift inside of a cooling tower at Springfield Nuclear Power Plant, but it isn't useful there and there also isn't exit from it. Despite that, Homer gets off from the lift and slips on the wall of the chimney.
