Cornholio

Beavis as The Great Cornholio.
After consuming large amounts of sugar or caffeine, Beavis sometimes undergoes a radical personality change, or psychotic break. In one episode, "Holy Cornholio", the transformation occurred after chewing and swallowing many pain killer pills. 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.
Though the “Cornholio” character was developed in the episode The Great Cornholio, Beavis first plays the entity as a passing gag in Generation in Crisis.

In some situations Beavis will refer to himself as
"the all mighty bungholio" One example is in the episode "Holy Cornholio" Beavis/Cornholio is inducted in to a cult that believes he is the reincarnation of there dead leader, at one point Cornholio leads the cultists in worship and chants/sings "I am the almighty bungholio" which he drags out at the bungholio part and this is not the only time Beavis does this in Beavis and Butt-head do Halloween Beavis transforms in to Cornholio and demands that the neighborhood kids demands that they give him "rolio" or Rolos after the kids run off and he picks up the Rolos Cornholio states the following, "Run as you may, you can not escape the wrath of the almighty bung hole, for I am the almighty bungholio. bungholio" the last time he says bungholio he's singing it as he walks down the street the kids ran down.

This character has become so popular that it can be found all over Google images, T-shirts, Image macros, Demotivational posters, Youtube mash ups, and even has some websites devoted to this one entity Bevis Ensues.One fan-site can be found here
