In '67, I made the mistake of laughing at a scrawny little guy that walked in a bar in Darwin we were partying in. He was only about 5'5". wearing Aussie Army tropics...boots, shorts, blouse, & dinker hat. He was OLD...at least fifty....& homely as a mud fence.
He was also S.A.S. ...w/ his squad behind him.
'Nuff said.
