Most of my friends were turned away.
I showed them my driver's license, and they wanted to know if I had any photographic evidence to prove who I am (i.e. not Santa Claus). I did happen to have a stack of snapshots in my pocket, a good 50-100 4" x 6" photos. I started sorting through them, and the pictures were not only not of me, but of people I didn't know--people I had never seen before.
The bouncers were getting annoyed at my inability to produce the required evidence. "Just a sec," I said, "I know there's a picture of me in here somewhere."
stoprockroll gave me a withering glance. "Chris," she said, "If you used iPhoto, all your images would be organized by subject and category and you wouldn't have this problem!"
