The show centers on two socially inept rock-loving teenage boys, Beavis and Butt-head (both voiced by Judge), who are roommates and live in the fictional town of Highland. They attend high school, where their teachers are often at a loss as to how to deal with them, although in many episodes, the two skip school. They occasionally work part-time at Burger World, and sometimes other side-jobs when people mistake their odd behavior as outgoing and assertive. Comedy is derived from their utter lack of conventional values such as work ethic. They are extremely obnoxious, misogynistic, and rude to almost every other character in the show and even to each other. They do not seem to realize this, however and seem to function on an instinctual level. They survive their often hazardous misadventures without serious consequences, though others around them don't fare as well. Mixed within each episode are segments in which Beavis and Butt-head watch music videos and provide humorous and bizarre commentary, improvised by Judge.
In 1996, the series was made into an animated feature film, Beavis and Butt-head Do America. On July 14th, 2010, it was announced that the series would be revived, and begin airing on MTV with new episodes.
