Mr. Van Driessen is a teacher at Highland High School in Highland, Texas. He is the teacher of Beavis, Butt-Head, Daria, Stewart and Earl.
He is a hippie by nature, who is very tolerant and understanding. He thinks Beavis and Butt-Head just need to be reached and their performance in school and intelligence will grow. He often tries to teach the boys valuable lessons and ends up getting harmed or nearly killed in the process.
