The sound comes from SpongeBob SquarePants, the long-running Nickelodeon cartoon about SpongeBob and his best friend Patrick Star, whose exaggerated emotions made the show a rich source of reaction audio online. Clips of the pair crying, like this waiting moment, circulate as a SpongeBob sad song for creators who want instant comic sadness without dialogue. Because the voices are instantly recognisable and the crying is so theatrical, the clip still works years later for memes about waiting, disappointment and overreactions.
