Beavis and Butt-head

Beavis and Butt-head are the titular protagonists of the franchise of the same name. They are best friends (and implied to be half-brothers).

Why They Rock

 * 1) They are a very hilarious duo.
 * 2) The duo's stupidity and crude jokes somehow never get old and can even be clever at times.
 * 3) "This sucks!"
 * 4) They work at Burger World, although they cause havoc there, they never got fired.
 * 5) They also got their movie called "Beavis and Butt-head Do America".

Bad Qualities

 * 1) They usually face zero consequences in most episodes and are scott-free from everything they cause.
