The Professor invents a machine that can scan an object and produce
two smaller copies, consuming matter provided to it in the process. He uses it to make smaller sweaters for himself, since he is shrinking and feeling colder as he ages.
Bender originally refuses the Professor's request to fold them, and then stores the replicator in his chest cavity and uses it to make two duplicates of himself so they can each fold one sweater. Before they can do so, the Planet Express crew and the duplicates are sent to deliver a shipment of personal hygiene products to an ugly giant alien humanoid who lives in a cave. He endures the crew's comments about his appearance until Fry inadvertently insults his mother, causing him to lash out and nearly destroy the ship before it escapes. Back on Earth, Bender's two duplicates copy themselves in order to get four cigars for Bender. The process continues until there are eleven generations of Benders running around the Planet Express building; the crew quickly moves in to exterminate all the duplicates, but Bender admits to setting one free. As this one gives rise to a new swarm that keeps reproducing and consuming matter, including Bender's couch and beer, the Professor worries that they will eventually eat all matter on Earth.
Leela points out that since the Benders are fueled by alcohol, they will run out of power once they have used up the world's supply. When this happens, the crew sweeps up the Benders and disposes of them. As the Professor takes a bath, he is surprised to find that the water in the tub has turned into alcohol. Some of the Benders survived and have reached the molecular scale, where they can synthesize alcohol directly from water and
carbon dioxide molecules. As a result, Earth's entire water supply becomes alcohol and its population gets extremely drunk. At this point, the giant alien arrives on Earth to apologize for his earlier outburst, even though the crew keeps drunkenly insulting him and
Zapp Brannigan tries to destroy him with a tank. Unable to get hold of the therapist who has been helping him deal with his anger issues, the alien flies into another rage and starts tearing up the city. Bender, the only sober crew member, agrees to fight the alien if Fry will fold the Professor's two sweaters. Bender uses the hordes of tiny duplicates to form a giant version of himself and fight the alien hand-to-hand. He loses the fight after insulting the alien's mother, but the swarm quickly consumes the alien, reducing him to dust. Bender urges them to help him solve other worldwide problems, but they are too lazy to take part and leave Earth instead. As the other crew members recover the next morning, the Professor is happy to note that someone finally folded his sweaters. When Fry asks Bender if he did this and learned a lesson about being lazy, Bender cryptically replies that perhaps he did, or perhaps he kept one of the Benders around to do the job for him. He then exhales cigar smoke, which turns out to be composed of thousands of microscopic and maniacally laughing Benders. ==Production==
