the st is the first two letters of my surname... the ark is the last three letters of my first name... making stark, sort of like a spoonerism of sorts. The ers got tacked on by my first wife after an incident involving our cat whining at the front door shortly after I'd gotten into bed, me being instructed to find out what was wrong with it and then having her shut the door behind me, turning on the entry light and highlighting to the entire neighbourhood that I was stark bollock naked and holding a whining cat.
Hmmm, would have looked rather suspicious to anyone who mave have happened to be looking out their window right about then, but thankfully none of the neighbours commented so I concluded that none of them had seen a thing.
One can look back in retrospect and say; "I should have put some pants on", but at the timel, I just wanted quickly to bring the cat in - after all, it was dark outside, and nobody was going to see anything - check to see if was hurt or something, put it back out and get back to bed. I mean, how was I to know she was going to creep down the hallway behind me, slam the door shut and giggle like all buggery when she turned on that confounded light.
So, starkers it was, and pretty much has been ever since.
