The chant comes from the theme song of Bill Nye the Science Guy, the PBS educational series that ran from 1993 to 1998 and made science cool for a generation of school kids. In the theme, a crowd rhythmically shouts his name over a driving rock riff before belting the show's title. Decades later the jingle resurfaced as a nostalgia meme across YouTube, TikTok and soundboards, where creators pair it with experiments, school clips and science jokes, keeping the bow-tied TV scientist's catchphrase alive as shorthand for learning something fun.
