i dont think he has the ability to laugh at himself cause his so fuked from drugs and booze, im sure he just does whatever the hell sharon wants him to, in turn, making a complete dick out of himself. Halford and Dio are different because they still have stage personas. you think halford wears all those studs offstage, i doubt it. he does it cause he hasthis whole "metal god" thing going for him, and it works, this goes with dio aswell. it might seem a bit odd for you but i cant see dio and halford not presenting themselves they way they do. anyways, to each there own.
