Bill Nye the Science Guy was an American educational television series that ran from 1993 to 1998, hosted by science communicator Bill Nye. Its theme song turned his name into a repetitive, call and response style chant that a generation of school viewers learned by heart from classroom screenings. Clips of the intro later circulated widely on YouTube and social media, where the chant became shorthand for science itself. It remains popular because it instantly frames any fact, test or explanation as entertaining, accessible and proudly nerdy.
