Hello Nurse comes from Animaniacs, the Warner Bros. animated series that first aired in 1993, where Yakko, Wakko and Dot would excitedly greet the studio nurse whenever she appeared. The line became one of the show's most quoted catchphrases, helped by its exaggerated delivery and the characters' obvious admiration. As clips circulated on video platforms and social media, it was lifted from its original cartoon context and reused as a reaction sound for attractive people, stylish outfits and surprising entrances. Its nostalgia and instant recognisability keep it popular with both longtime fans and new meme creators.
