Beavis and Butt-Head began as an MTV animated series created by Mike Judge in the early 1990s, built around two lazy teenage metal fans whose stupidity drives every scene. Beavis developed a hyper alter ego, usually called Cornholio, after too much sugar or caffeine, pulling his shirt over his head and ranting about his bunghole. Lines in that voice became some of the show's most quoted material, and short clips kept circulating on soundboards and in meme edits long after the original run, especially for deliberately uncooperative replies.
