Fry believes that a human life is more important than a robot life, so Bender decides to kill himself again, only this time he really follows through. But instead of dying he turns into a ghost that haunts Fry.
The episode contains three separate stories. In the first, which parodies the 1930s B&W cartoons, Fry wants to propose to Leela, so he blows up a comet made of "dimondium" to make her a diamond ring. In the second, which parodies the 1980s video games, the Professor invents a microscope with an infinite magnification and learns all the secrets of the Universe, which puts him and other scientists out of business. In the third part, which parodies Japanese anime, the team must defend Earth from dancing aliens.
