I am sark because I was watching an episode of ALIAS.  The bad guy from ALIAS is called Sark.  I couldn't really think of a name and didn't want to use my real name, Lewis.  So that is why I got it.  There was no real thought in it, it just happened. I am glad I wasn't watching BARBIE the cartoon or the Teletubbies.. 

The 79 part is the year I was born, well two days before the end of 1979.  
I was Sark on pokerstars and VC. So I just kept it for Blonde.
