Mystery Science Theater 3000: Movie Plot: The Human Duplicators An alien has been sent to Earth to duplicate people and take over the planet. Intro: Joel asks the 'bots what modifications they want. Tom has several sketches of complete redesigns. Segment One: The Mads (in between giggle fits)invent the Fridge Alarm, to prevent William Conrad from breaking in. Joel invents the beanie-chopper: a beanie that flies. Tom and Crow aren't impressed, because they thought Joel would go through the roof. Segment Two: The crew makes models of the spaceship from the movie out of household items. Tom and Crow don't seem enthusiastic. Segment Three: Servo duplicates himself several times. Joel pulls him aside, and the duplicates attack Crow. Segment Four: Hugh Beaumont visits the SOL again, and he is very cranky. Segment Five: The 'bots out themselves... as robots. Joel already knows. William Conrad breaks into the Mads' fridge. Stinger: Thor androids fighting each other.
