At Springfield Minimum Security Prison,
Sideshow Bob is disturbed when he hears the other inmates laughing at the inane antics of
Krusty the Clown's television show. Believing that television is a fountain of "mindless drivel" and wanting to rid the world of it, Bob escapes while on work duty at a local Air Force Base. By mimicking one of the base's colonels he gains access to a restricted area of the hangar, where he steals a 10-megaton
nuclear weapon. As the Simpsons and other residents of Springfield are attending an
air show held at the base, the signal on the big screen is interrupted by Bob, who threatens to detonate the bomb unless Springfield disables all of its television broadcasts. Upon hearing the announcement, everyone flees the airfield in panic, except for
Bart and
Lisa. Unable to locate Bob, Mayor Quimby decides to give in to Bob's ultimatum. Krusty, refusing to submit to Bob's demands, takes refuge in a
civil defense shack in the desert, which he uses to transmit a heavily improvised show. Lisa deduces that the unusually high-pitched voice of Bob in his broadcast was due to
inhaling helium, and locates him in the envelope of the Duff blimp. Bob, having lost his patience thanks to Krusty, tries to detonate the bomb, which turns out to be a
dud, because it had passed the
expiration date of November 1959. Lisa alerts the police to Bob's location using the blimp's
variable-message sign, but Bob deflates the blimp and kidnaps Bart, before stealing the original
Wright Brothers aircraft, which had been an
exhibit at the air show. Holding a knife against Bart's throat, Bob attempts to carry out a deadly
kamikaze attack against the civil defense shack where Krusty is hiding and kill him, Bart, and himself, but the slow-moving plane ends up merely bouncing harmlessly off the shack. The authorities quickly arrest Bob and take him back into custody while Bart is reunited with the rest of the family. ==Production==
