"Radio Bart" is the thirteenth episode of The Simpsons' third season. It originally aired on the Fox network in the United States on January 9, 1992. In the episode, for his birthday Bart receives a microphone that transmits sound to nearby AM radios, and also uses a labelmaker to put "Property of Bart Simpson" on all his possessions. To play a prank on the citizens of Springfield, Bart places a radio deep inside a well and uses the microphone to trick the town into thinking a little boy is stuck in it. He enjoys the prank until Lisa reminds him of the "Property of Bart Simpson" label stuck to the radio. Whilst trying to retrieve it, Bart gets trapped in the well. Still smarting from his prank, the town leaves him down there. Eventually Homer decides to rescue Bart by himself.
