Mr. Stevenson

Mr. Stevenson(Stewart's Father), Is a Beavis and Butthead villian.

He is A middle-aged male. In early episodes, he is a teacher at Highland High . Later he is a businessman, judging from his cell phone  and references to "the office" . He is a regular victim of Beavis and Butt-head's destructive shenanigans, such as having his house blown up  or vandalized , being involved in a car accident by following wrong traffic directions , or having his own phone forcefully inserted into his rectum,  when Beavis and Butt-head accidentally lead prank-call victim Harry Sachz to his house. He tries to come off as a caring and responsible family man, but he reveals his cowardly nature in times of distress, invariably trying to shift blame to Stewart . He has a large collection of pornographic magazines, which Beavis and Butt-head know the exact location of. It is implied that he is impotent in  Sperm Bank when he visits a sperm bank with his wife. He is voiced by Mike Judge.

Like Principal McVicker, and Bradley Buzzcut, he hates Beavis and Butt-head
