The Day the Earth Stood Stupid

"The Day the Earth Stood Stupid" is the thirty-ninth episode of Futurama, the seventh of the third production season and third broadcast season. It aired 18 February, 2001 on FOX. A mystic fleet of brains travel the universe and turns every into idiots, and now the turn has come to Earth. Nibbler explains her plan to Leela and explains how Fry is the key to solving the attacks by the brains.

Act I: "All glory to the Hypnotoad!"
One day's brain flight from Earth, the planet Tweenis 12 is destroyed by a swarm of flying brains.

Meanwhile, on Earth, Leela enters Nibbler in a pet competition. She hopes to win since she put Nibbler through strict training, but it is apparent she has just been spoiling him because his half-hearted attempts are so adorable. After learning the prize is five hundred dollars and a year's supply of dogfood, Bender and Zoidberg decide to enter themselves. During the sheep-herding competition, the Hypnotoad displays his amazing abilities (both on the sheep and the judges). On Nibbler's attempt, he simply devours the sheep.

Bender enters Zoidberg into the contest, claiming him to be a "Hard-Shelled Whooping Terrier". Bender forces Zoidberg through the obstacle course, then through a talent competition, by whipping him. Leela tries to get Nibbler to perform, but is unable. Nibbler sees a pig-shaped balloon and attacks. The balloon pops and launches Nibbler high into the air, after which he lands in a bowl of milk, splashing people with the milk and causing them to be attacked by dozens of cats.

Bender and Zoidberg get second place, losing to the Hypnotoad, whose win was most likely illegitimate (though no-one notices, thanks to its powers). Leela and Nibbler are awarded "Dumbest Pet in Show".

Act II: "I guess I'll have to eat this raw, dripping ham by myself!"
Back at Planet Express, Leela accepts that Nibbler may be dumb, but Fry sticks up for him. The Professor enters with "good news" about the destruction of Tweenis 12. Hermes points out that there have been a string of such planetary destructions, and Fry (with the help of Leela) points out that Earth is next. Nibbler gets anxious and runs away.

Leela attempts to track him down in an alley, luring him with a ham. She encounters a dumpster emitting an ominous light from within. As Leela cautiously approaches, a giant floating brain emerges. Leela is chased through the alleys by several brains, where she sees Nibbler donned in a mysterious body suit and pulling a small spacecraft from a shed. He takes off and waves goodbye, but Leela begs for him to come back as she tries to hold off the floating brains. Nibbler decides to return to Leela, and she jumps into the extremely cramped little ship where they escape.

Act III: "I thought you were a furry little moron!"
The floating brains continue their attack on the Earth, engulfing entire buildings in a blue glow, including the Planet Express building. Bender is concerned that his heart has stopped beating and that his skin is hard and clanky, but Fry points out that he doesn't have a heart and that he's made of metal. The Professor and Zoidberg are acting equally stupid.

Nibbler and Leela are flying through space, and Nibbler transmits his thoughts directly to Leela's brain to communicate. Nibbler explains the situation to Leela, and informs her that they're going to his home planet. Then he tells her how the universe began, and Leela realizes that every religion is wrong.

Hermes is standing with his mouth open in the shower. Fry turns on the news and finds that the news anchors are acting stupid as well. The PE crew then expresses a desire to play the lottery, buy internet stock (on margin), and join the Reform Party. Fry finally understands that they aren't just acting strange, but have indeed become idiots.

Nibbler and Leela finally arrive on Planet Eternium, at the exact center of the universe, and land at the Hall of Eternity, which is ten miles west of the exact center of the universe. After this point, we hear Nibbler speak not in mindless garbled chattering, but with a deep and dignified voice in English. Other creatures that look like Nibbler are waiting inside, and greet Nibbler as "Lord Nibbler, Ambassador to Earth". However Nibbler points out that the name "Lord Nibbler" is for Leela's sake. His own name would be impossible (and time-consuming) to pronounce. One millisecond after the universe was created, a terrible enemy known as the Brain Spawn came into existence. This explanation is interrupted by "the Feast of a Thousand Hams."

Nibbler explains that the Brain Spawn are attacking all intelligent life, as they hate all consciousness; the thoughts of others are unpleasant to them. They travel from world to world, making everyone stupid to wipe out all thought in the universe. Nibbler then indicates that Fry is the hope of the universe, as he is immune to the Brain Spawn's attack. Fry, meanwhile, tries to help the people of New New York, but foils himself because though he is smarter than everyone else on Earth at this point, he is still pretty stupid...

Act IV: "Time to re-educate you duncebags!"
The Nibblonian fleet approaches Earth. It is explained why Fry is immune to the Brain Spawn's attack: Fry's immunity is due to his lack of the Delta brainwave, due to other events which have not happened yet. Leela is sent to instruct Fry to locate and attack The Big Brain, but she cannot be trusted to complete this task, since she'll be affected by the Brain Spawn's stupifaction rays once she lands on Earth. The Nibblonians pin a note to Leela's shirt and send her off.

Fry is attempting to re-educate the PE crew, but even George Washington's head forgets who was the first president of the United States. Leela suddenly crashes through the window, and attempts to communicate with Fry, but she's been turned dumb. She hands him the note, but he misunderstands and blows his nose on it. Then he throws it in the fire, and Leela tries to retrieve it, only to discover that fire is hot. The Professor confirms her conclusion. Leela tries again to communicate, then points out the flying brains outside the window. Leela tells Fry to find the biggest brain, and Fry concludes that he might find it at the library.

Fry and Leela run to the New New York Public Library, and Fry confronts the Big Brain in the Ancient Literature room, where it is absorbing the knowledge of the human race. The Big Brain attempts to stupefy Fry, only to find him immune. Fry throws a book at the it, but the Big Brain is impervious to physical attack. Fry tries to think of another plan, and finds that his thoughts cause pain for the Big Brain. Fry frantically searches through a pile of books to find a book to make himself think. He reads the book, which causes the smaller brains outside to fall from the air. The Nibblonians prepare to land in order to clean up the mess.

The Big Brain then uses his abilities to take Fry and Leela into the world of Moby Dick. Fry almost attacks the Big Brain, but Queequeg stops him, on the grounds that it's not a white whale, but a grey thinky whale. The Big Brain escapes, and Fry, Leela, Queequeg, and Captain Ahab follow. They end up in Tom Sawyer, where they meet the eponymous character, who has tricked the Big Brain into whitewashing the fence. The Big Brain tries again to escape, and pulls everyone into Pride and Prejudice. Fry throws Tom Sawyer's whitewash onto the Big Brain, and Captain Ahab proclaims him to be white now, and he and Queequeg begin assaulting him. Fry gets an idea and jumps out the window.

Act V: "The big brain am winning again!"
Fry escapes from the Brain's field, and climbs a bookshelf. He attempts to electrocute the Big Brain with a broken chandelier, but crashes into the wall. A bookshelf then falls on top of him, breaking his neck. Leela tries to help, but Fry dies. The Big Brain laughs in triumph, but the Fry on the floor disappears, revealing that Fry is writing a book of his own. The Big Brain is trapped in this new book (filled with plot holes and spelling errors), in which Fry causes the Big Brain to leave Earth for no reason. The Big Brain falls for the trick, and flies off.

Outside, the Nibblonians "clean up" by consuming the fallen Brain Spawn. The population of Earth is returned to their normal levels of intelligence, but the process forces them to forget the entire incident. Only Fry remembers, but nobody believes him, nor do they really care. Nibbler returns to Leela to remain in disguise until the next time he is needed to protect the universe...

Trivia

 * The plot of this episode draws heavily from Star Trek episode #29, "Operation: Annihilate!" in which a string of planets are destroyed by space-bound brain cells that cause their victims to act suicidal.
 * The planet Tweenis 12 is a reference to the fact that children aged 12 are called "tweens" because they're (supposedly) not children and not yet teens. According to the commentary, the word "tweenis" is also a synonym for a part of human anatomy sometimes called the "taint".
 * Madison Cube Garden's sign reads "Champion Pet Show Today" "Kids: See Toucan Sam's Death Mask". Toucan Sam is the mascot for Fruit Loops, making another cereal reference.
 * One booth at the pet show is for "Soylent Chow"; The picture shows a dog surrounded by the recycling symbol. The reference could either be for the butchering of humans as pet food or cannibalism of canines.
 * Frank Welker plays both Nibbler's animal voice and his speaking voice.
 * This episode was named #18 on IGN's list of Top 25 Futurama Episodes.
 * Bender's line "Hey, let's all join the Reform Party!" was changed to "Hey, let's all join the Tea Party!" in current broadcasts.
 * The first book Fry and Leela are trapped in is "Moby-Dick". A later episode, "Möbius Dick" would draw from it.
 * The second book Fry and Leela are trapped in is "The Adventures of Tom Sawyer". The song "Tom Sawyer" by Rush would appear in "Anthology of Interest II".

Fast Forward

 * Planet Eternium is visited again in "The Why of Fry", where Nibbler again displays his ability to speak.

Goofs

 * The booths at the pet show seem to move around in order; Kibbles & Snouts starts next to the Soylent Chow booth, then an information booth is placed where K & S should be, and then the Cream booth ends up between K & S and Soylent Chow. This could be explained by multiple booths in different places.
 * When Fry holds the head of George Washington, the letters spelling his name shift from upper to lower case.
 * In one scene in the Planet Express employee lounge, Bender is cross-eyed.
 * After the bookshelf collapses on Fry, the purple ray from the Brain to Leela has disappeared.
 * Fry's writing does not appear in his book, Fry Tricks The Brain.

Allusions

 * The title of the episode is a reference to the 1951 classic sci-fi film The Day the Earth Stood Still.
