Beavis is the more dumber of the duo, has an obsession with fire (which caused controversey), uses toliet humor a lot, but overall somewhat well-meaning and nice in his own weird way. He is shorter than Butt-Head, though he might seem taller because of his hair. When approaching chicks, he doesn't use the smug pick-up lines that Butt-Head does, typically saying something like "Hey, how's it going?" When girls do rarely show interest in them, he usually is the one who gets the attention. Beavis has a little chuckle/laugh/grunt that goes "Heh heh" or "Meh heh heh". Beavis does it so often that it is basically the way he breathes. He and Butt-Head work at a fast food resturant called Burger World, where he is a fry cook. His mother is a ignorant slut named Shirley Beavis, while his father was a Mötley Crüe roadie, and they both met (along with Butt-Head and his dad) in "Beavis and Butt-Head Do America", but never realized they were father and son. Beavis often follows Butt-Head around everywhere they go, Butt-Head saying in "Beavis and Butt-Head Do The Universe" that Beavis is, "not really my friend, he just follows me around." If you couldn't tell, Beavis is my favorite character. Um, pretend there is more words here. Blah blah blah...
Butt-Head is the 'leader' of the duo, being described by The Boston Phoenix as, "ringleader, the devious visionary." Butt-Head is the more calmer, slightly smarter, and cockier; being overly confident in everything he does, no matter how stupid. He often slaps Beavis, calls him names such as 'Butt-knocker', yells at him, and sort of just pushes Beavis around. Sometimes, but not always, Butt-Head will compliment Beavis. It is really depending o the writer of the episode, though. Butt-Head's main goal is to 'score'. He will approach a woman with the more direct line like, "Hey baby", oblivious to the discomfort from her. Butt-Head wears braces, but as a adult, he does not. Butt-Head has a little chuckle/laugh/grunt that goes "Huh huh" or "Uh huh huh huh". Butt-Head does it so often that, at this point, the way he breathes... Beavis and Butt-Head work at a fast food resturant called Burger World, where he is a cashier there. His mother is seen in "This Book Sucks", while his father was a Mötley Crüe roadie, and they both met (along with Beavis and his dad) in "Beavis and Butt-Head Do America", but never realized they were father and son.
