Mine has its origins in a tale of two brothers-in-law.
A few years ago, one of them discovered Photoshop, and all the wonderful things that you can do with that software. Well, this was one of his first efforts:
Needless to say, I have been “Skid Mark” ever since. I guess that's better than being Vanilla Ice or something like that? (maybe not!!)
Another brother-in-law (who also now has a new “rapper” identity, and his face immortalized on a slightly modified cover of Vibe magazine) rechristened me “Uncle Skid” when his twin daughters were born two years ago.
Yes, Virginia, there is a real Uncle Skid. "Ya better check yourself, 'cause Skid Mark's in da house!"
