The line comes from Courage the Cowardly Dog, the Cartoon Network series created by John R. Dilworth that ran from 1999 to 2002 and followed a nervous pink dog protecting Muriel and Eustace Bagge in Nowhere, Kansas. Clips and lines from the show have stayed in circulation through reruns, cartoon edits and soundboards, where short insults are easy to lift out of context. This one survives because the joke needs no setup: the formal wording and blunt subject make it reusable whenever a bald character, actor or friend appears on screen.
