 * An Alien appears in Hanger 18. This is a reference to to the Roswell NM ufo crash in the '40s, where it was said that the aliens and spaceship parts were held in Hanger 18 of the Wright-Pattrsoin airforce base.
 * At one point, Milhouse plays with the cockpit of an F-15 and tries to act like he is blasting his mom, dad, and Sally Waxler out of anger that he had to be sent to a psychiatrist. According to the DVD Commentary, this scene was what inspired them to create A Milhouse Divided, the episode where his parents divorced.

 * While setting up the nuclear device, Sideshow Bob is whistling 'We'll Meet Again' a song used in the 1964 film Dr.Strangelove or: How I Learned To Stop Worrying and Love The Bomb, a film about nuclear deterrence which ends in the world being destroyed by nuclear weapons

Goofs

 * Lisa says that helium changes one's voice. However, that is only achieved if helium is absorbed into one's vocal cords. Mere insufflation of helium, as was the case with Sideshow Bob hiding inside the blimp, is too weak to cause the well-known effect. This is shown when the blimp deflates and covers Lisa, her voice does not become higher.
 * When Sideshow Bob first shows his evil plan on the Jumbo-Vision, his voice is not higher pitched. This is first referenced when the guard says, "I hate that guy and his stupid high-pitched voice."
 * Harriers are not flown by the US Air Force.
