The line comes from SpongeBob SquarePants, where Patrick Star mans the Krusty Krab phone and gets frustrated by callers asking if it is the restaurant. The English scene became a long running meme for stubborn denials, and the German dub version, captioned as the angry or evil take, spread separately on soundboards and in edits. Its exaggerated rage made it reusable far beyond the episode, as a standalone shout for correcting people in the most dramatic way possible.
