"Shut up before I kick your ass!"
Butt-head is the more prominent leader of the duo, and Beavis's best friend. He's a more slower character than Beavis, and Mike Judge has noted that he appears to have just a bit of common sense while Beavis has none. Butt-head usually smacks Beavis around, and threatens him. In an episode, they nearly killed each other and Butt-head was arrested, but Beavis didn't press any charges. More will be added to the article soon.
