Beavis and Butt-Head are two high-school teenagers who spend their time watching TV and making jokes about bodily functions.
They're big fans of heavy metal music (Beavis wears a Metallica shirt, and Butt-Head wears an AC/DC shirt).
They're obsessed (naturally) with women, and their feeble attempts at understanding them account for their feeble attempts at, in their own words, 'scoring with chicks'.
Created by Mike Judge (King of the Hill, Office Space), the Beavis and Butt-Head animated cartoons were flighted on MTV between 1993 and 1997.
