Sideshow Bob's prison number in this episode is A113. A113 is a little known easter egg Brad Bird puts in his movies and films, such as this one, all the Pixar films, two other Simpsons episodes ("Krusty Gets Busted" and "Cape Feare"), and many other films and cartoons.
An Alien appears in Hanger 18. This is a reference 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.
- In The Simpsons Road Rage, the alien's UFO appears in the hangars of Springfield International Airport.
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.
After Sideshow Bob demands that all TV must go, Dr. Hibbert says "Surely he doesn't mean VH1".

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 only mildly higher pitched, compared to later in the episode when the helium affects Sideshow Bob's voice. This is first referenced when the guard says, "I hate that guy and his stupid high-pitched voice."

Colonel Hapablap shouts "Sideshow Bob, what is your major malfunction?!" a la Gunnery Sergeant Hartman (also played by R. Lee Ermey) in Full Metal Jacket.
