The Simpsons - Season 23 Episode 17 -

Mr. Burns replaces all of Springfield Power Plant's employees with robots (guest voice Brent Spiner) but decides to keep Homer as the sole human worker. With unemployment at an all-time high and mechanical arms operating the workplace, Springfield becomes a dismal and humorless place. But when Homer's machine-programmed peers start to turn on the community and his former real-life employees come to the rescue, they all realize that robots can't replace human friends.
