The greeting comes from SpongeBob SquarePants, the Nickelodeon animated series created by Stephen Hillenburg that premiered in 1999. SpongeBob's relentless hellos to Squidward are a running part of their neighbor dynamic, and short clips of the line spread online as a reusable greeting meme on social media and soundboards. It sits alongside other enduring SpongeBob clips like the spongebob sad song and the recurring My leg! gag, staying popular because almost any friendly entrance can be made funnier with SpongeBob's voice.
