The line comes from SpongeBob SquarePants: Battle for Bikini Bottom, a 2003 video game based on the animated television series. Mrs. Puff, SpongeBob's boating school teacher, delivers the warning with the strict, anxious authority associated with her character. Short clips of the dialogue later circulated as reaction audio because the statement works outside its original scene. It remains useful in gaming videos, cartoon edits, and social posts where a creator wants to suggest that curiosity may lead to an unpleasant answer.
