The Simpsons Episode 7.09 Sideshow Bob's Last Gleaming

Lax prison security makes it possible for Sideshow Bob to escape from prison yet again. This time, however, he's less interested in killing Bart Simpson as he is in knocking out Springfield's television stations, since he's grown to detest TV so much while in prison. Bob sneaks onto the Springfield air base on the day of the big air show, commandeers an atom bomb, and threatens to blow-up the crowd if the mayor doesn't end all TV broadcasts. When the bomb fails to explode, Bob returns to an older, more familiar plan and kidnaps Bart. That plan is also foiled and Bob returns to prison, again.
