Cornholio is the hyperactive alter-ego of Beavis. He turns into this in many episodes and other media. Cornholio is an iconic aspect of the series, and arguably the most popular. When Beavis consumes large quantities of sugar, caffeine and other stimulants, he will begin to exhibit symptoms of convulsions, rapidly shake his head, and gaze cross-eyed at his own fist. When a Spanish sounding word is spoken or mentioned, Beavis undergoes what appears to be a total personality change into Cornholio.
