Futurama Episode 6.16 Ghost in the Machines

During an accident at the annual city Parade Day, Bender witnesses Fry save a human, and not a robot, from being crushed to death. Incensed that Fry believes a human life to be worth more than a robot's, Bender goes to the nearest suicide booth. However, the Suicide Booth in question turns out be his ex-girlfriend Lynn who murders Bender for dumping her. Because of the "murder," Bender becomes a ghost stuck in an infinite loop in robot limbo, where his software operates on the global wireless network. Unable to interact with anything or communicate with anyone on Earth, Bender is annoyed until he finds that the Robot Devil can hear and see him. The Robot Devil declares his anger with Fry over having been stuck with his hands (in "The Devil's Hands Are Idle Playthings"), and makes a deal with Bender that he will return him to his body if he scares Fry to death. If Bender fails, he will be damned to Robot Hell for all eternity.
