- Bill Nye's nickname of "Bill Nye the Science Guy" actually stemmed from his time working on a sketch comedy television show in Seattle called "Almost Live!" When fellow show host John Keister mispronounced the word 'Gigawatts' while quoting Back to the Future, Bill corrected him, leading to John saying, "Who do you think you are -- Bill Nye the Science Guy?" The nickname stuck ever since.
