I don't normally post things like this on here, but... here's some website's idea of which "celebrities" I look most like. Who is that on the right, hiding behind Richard Gere? Could it be... David Hilbert, famous mathematician best known for his immensely important list of 23 problems fundamental to mathematics?! Check out his photo in that first link -- very stylish.
I also appreciate that a computer somewhere thinks I look like Janeane Garofalo. Very interesting.
Back to real photos soon! Until then, enjoy this ultra-rare Dave-all-dressed-up photo.
