After the credits roll in the original series finale, the following message appears: "Thank you to all the talented artists, writers and highly intelligent people who worked so hard to make Beavis and Butt-head look so dumb."
Before each episode, the following warning appears: "Beavis and Butt-Head are not role models. They're not even human; they're cartoons. Some of the things they do would cause a person to get hurt, expelled, arrested, possibly deported. To put it another way, DON'T try this at home"
The title screen for each segment is often animated in a comical way that reflects the content of what is to come. For instance, "Tired" features the title rolling on to the screen like a spinning tire.
In Canada, the intro always said "Warning, warning extreme bad taste alert people, this comedy may offend some viewers so viewer discretion is advised ok"
For the first few seasons the disclaimer was: Beavis and Butt-head are not real. They are stupid cartoon people completely made up by this Texas guy who we hardly even know. Beavis and Butt-head are dumb, crude, thoughtless, ugly, sexist, self-destructive fools. But for some reason, the little weinerheads make us laugh.
