"Many, Many Monkeys" is an episode of the television series The Twilight Zone, first broadcast in 1989. The episode was written in 1964 for the final season of the show's original black-and-white run by producer William Froug, but though CBS bought the script, they chose not to use it. Froug believed that they found it "too grotesque." It remained shelved for more than twenty years until it was made as an episode in the third and final season of the 1980s Twilight Zone revival.
