Premise: "The Day the Earth Stood Stupid" is the seventh episode in season three of "Futurama". It originally aired on the Fox network in the United States on February 18, 2001. The title of this episode is a play on the title of the 1951 science fiction film, "The Day the Earth Stood Still".
Hypothesis: The Day the Earth Stood Stupid was not the first episode title that was inspired by an early science fiction film.
