Why did so many people genuinely believe they remembered hearing this on broadcast television? The answer lies in the mechanics of mondegreens, misheard phrases caused by ambiguous auditory input, combined with the fragility of childhood memory. The human brain constantly attempts to match noisy signals with familiar vocabulary.
The original track features a rapid vocal section where the chorus quickly chants "Bill Nye the Science Guy" multiple times over high-speed percussive fills. In typical broadcast environments, such as a hollow classroom with a cathode-ray tube television mounted in the corner, acoustic clarity was poor. The rapid-fire /s/ and /g/ consonants easily blurred into mush. When a suggestive online meme tells a listener to anticipate "your mom's a guy," top-down cognitive processing takes over. The brain retroactively forces the acoustic waveform to match the expected phrase.
Psychologists refer to this as a form of the Mandela Effect, driven by collective social suggestion. You did not hear the insult on television in 1996; you heard a dirty joke on your phone in 2015, and your memory rearranged the 1996 TV memory to accommodate the punchline.
