I feel a little guilty slamming the ass of Mel Gibson, but given the ugly, and dramatic fall of the once respected actor, makes a pictorial history of ass simply too easy. Admittedly, in the late 80's and early 90's I respected his work, and coveted his bounty, not to mention his Lethal Weapon. Times, they do so change however and it is doubtful that Gibson will ever get any semblance of a career back.
