The series’ central characters are teenagers Beavis and Butt-head who live in the fictional town of Highland, Texas. They attend high school, where teachers are often confused by their antics. They occasionally work part-time at Burger World, and they also occasionally get other jobs when people mistake their strange behavior as responsive and assertive. The humor lies in their complete lack of traditional values such as work ethics. Both of them are extremely disgusting and rude to almost every character on the series, and even to each other. They themselves, however, apparently do not realize this, and act instinctively. Beavis and Butt-head get out of their dangerous misadventures without serious consequences, while the people around them do not always succeed. A central part of each episode is Beavis and Butt-head’s poignant commentary on MTV’s music videos, what happens in each episode. Beavis and Butt-head are in 9th grade. During the cartoon, they said more than once that they were 15 years old.
