C'mon, you know you want to.
I use that photo, which is an outtake from an old headshot photo session from 2008, to draw your attention to my facebook fan page. Yes, I have one! Won't you like it?
And why am I making that face? Because I'd been smiling for an hour, and I had to flex my face muscles. Not a bad way to do it.
