The sound comes from the opening of SpongeBob SquarePants, the animated television series that first aired in 1999. Its intro music became widely recognizable through years of TV broadcasts, clips, and reposts online. Short cuts of the opening are commonly used in meme edits because they establish a playful tone almost immediately. The clip remains popular because SpongeBob has a long internet afterlife, and even a very short piece of the intro is enough for viewers to recognize the reference.
