Mrs. Puff has been SpongeBob's long-suffering boating school teacher since SpongeBob SquarePants began in 1999, and her inflating like a pufferfish is one of the show's most repeated visual gags. Short clips of the gag spread on soundboards and in edits alongside other SpongeBob staples like the a few moments later transition, turning the puff into a standalone reaction. Editors now isolate the air blast on its own, so the inflation joke lands even without the cartoon footage, which is why it remains popular for quick meme cuts.
