'Futurama': 'A Farewell to Arms'
2012 Twentieth Century Fox Film Corporation 'Futurama': 'A Farewell to Arms'

In "A Farewell to Arms," the second half of last night's two-episode season premiere of "Futurama" on Comedy Central, a select group of Earth's residents fled to Mars after an ancient prophecy wheel was discovered that seemed to indicate this planet was about to be destroyed by solar flares. Really, this was just another typical day in the 31st century, where the world always seems on the verge of destruction -- fitting for a series that often spoofs sci-fi standards. Here's a rundown of some of the other times the Earth almost ended on the Matt Groening-created series:

Futurama Giant Piece of Garbage

"A Big Piece of Garbage": Season 1, Episode 8

Thanks to Professor Farnsworth's invention of the Smelloscope, which allows people to sniff for distant cosmic objects, the Planet Express crew discovers a giant ball of garbage hurtling toward New New York City. It turns out to be 20th-century trash returning home after having been shot out into space a thousand years ago, and to save everyone from being annihilated by a gob of America Online floppy disks and coffee grounds, Fry has to teach the refuse-free future how to litter in order to create an equal-sized garbage ball that they can shoot back at the incoming one. Problem solved! Or at least delayed for another millenium or so.

Futurama When Aliens Attack

"When Aliens Attack": Season 1, Episode 12

The warlike residents of Omicron Persei 8, a thousand light years from Earth, invade because a long-ago broadcast of the "Ally McBeal"-like "Single Female Lawyer" (about, as Omicronian Emperor Lrrr explains, "an unmarried human female struggling to succeed in a human male's world") was interrupted by what turns out to have been an act of klutziness by 20th-century Fry. It may be one of the worst reasons ever to attack and threaten to destroy a planet, but who can fault a dedicated fan? Since videotapes were destroyed in 2443's second coming of Jesus, the Planet Express crew ends up re-enacting a version of the show based on Fry's vague memories of it, proving that watching a lot of TV can actually help you save the world.

Futurama Mothers Day

"Mother's Day": Season 2, Episode 14

When Mom, the beloved corporate overlord of Mom's Friendly Robot Company, decides to become "supreme overlord of Earth" because she's feeling bitter about an ages-ago affair that went sour, she decides to doom the human race to extinction for Mother's Day so that "everyone will hate it as much as I do." She uses her powers as manufacturer of the world's robots to start a robot rebellion that sends people screaming through the streets as giant androids tear down buildings, TVs attack and Bender... acts normally. It's then up to Professor Farnsworth to rescue everyone with a feat of elder love.

Futurama Day the Earth Stood Stoopid

"The Day the Earth Stood Stupid": Season 3, Episode 7

Giant floating brains turn out to be Earth's greatest nemeses in the universe of "Futurama" -- we first see them in this episode, in which the Brainspawn attack the planet and render everyone an idiot with their stupidity rays. Only Fry is immune, but he's never been the brightest bulb in the basket in the first place. He does, however, have enough knowledge to divine where the leader of the invading force resides by thinking about where brains would obviously hang out -- at the library. Fry traps the Big Brain in a story of his own creation ("a crummy world of plot holes and spelling errors") and makes him leave the planet "forever, for no raisin" -- one of the show's great line deliveries from Maurice LaMarche.
