SpongeBob SquarePants premiered on Nickelodeon in 1999, created by marine science educator Stephen Hillenburg. Its theme, performed by Patrick Pinney as Painty the Pirate, became one of the most recognised cartoon openings on television, repeated at the start of hundreds of episodes and films. As episodes circulated online, the opening was clipped for memes, remixes and reaction videos, often to signal something childish or absurd. Its call and response structure makes it easy to recognise, quote and reuse decades after the series began.
