Professor Farnsworth invents a duplication machine that can create two smaller copies of anything. Bender, ignoring the lessons of an episode of “The Scary Door,” uses the machine to make copies of himself to do his work for him. His duplicates, however, are just as averse to doing the work as he is… and just as obnoxious. The Benders keep duplicating themselves, forming a society of increasingly tiny Benders... and threatening to consume all the matter on Earth, completely over-running the planet. The Planet Express crew attempts to exterminate the existing duplicates before it's too late, but one escapes and continues duplicating. An unexpected solution presents itself due to Bender's unique power source... but the solution quickly morphs into another crisis, which becomes an even bigger crisis thanks to a Giant Unattractive Monster the Benders once insulted.
