After consuming large amounts of sugar or caffeine, Beavis sometimes undergoes a radical personality change, or psychotic break. He will raise his forearms in a 90-degree angle next to his chest, pull his shirt over his head, and then begin to yell or scream erratically, producing a stream of gibberish and strange noises, his eyes wide. This is an alter-ego named ‘Cornholio,’ a normally dormant persona. Cornholio tends to wander aimlessly while reciting ‘I am the Great Cornholio! I need TP for my bunghole!’ in an odd faux-Spanish accent. Sometimes Beavis will momentarily talk normally before resuming the persona of Cornholio. Once his Cornholio episode is over, Beavis usually has no memory of what happened.
In the guise of Cornholio, Beavis becomes a successful beat poet (Buttniks), and in ‘Vaya Con Cornholio’ he is deported to Mexico after wrongfully being subjected to immigration detention by an agent of the INS. During his detention the agent and his superior attempt to make sense of the gibberish that is Cornholio, going so far as to look up the definition of ‘bunghole.’ In that same episode, he claims to be from Lake Titicaca, but when asked where it was, he responded with ‘Nicaragua,’ despite the fact that Lake Titicaca is in Peru/Bolivia.
