When I was a kid, I told my grandfather I wished my dad had been a war hero. Grandpa said if he had been he might not have survived and I might not have known him. After that, having Sergeant Rock for a dad didn't matter so much.
Here though he looks a little like Lee Marvin or maybe Donald Sutherland from The Dirty Dozen, which is cool in itself.
He would have been 73 today.
