Decisions decisions..... this is a toughie. They both have their own unique outstanding qualities but I would have to say Butthead because he has been known to rock an AC/DC T shirt.
When I went out for the football team, where no one knew me, someone started calling my Beavis because I reminded him of the character, and then other people agreed and the name stuck. I have no idea why though, as I have never watched a second of that TV show.
I guess I'm not that surprised that the show is back on. It was awesome back in the day. I'm gonna have to choose neither. They're too young for me :) I'm goin with Carl from aqua teen hunger force. He don't need no instructions to know how to rock!
