The line comes from the time cards in SpongeBob SquarePants, the Nickelodeon animated series that first aired in 1999, where a narrator announces how much time has passed between scenes. Clips of the card spread through YouTube compilations and later TikTok and Instagram edits, where creators borrowed it to mark their own time jumps. It remains popular because almost everyone recognises the voice and the format instantly, so a single short line can set up a joke without any explanation.
