How should I pose for my license photo?

You dont get to choose how you're posed. They just throw you in front of the background and snap the picture. If you try and personalize it at all, turn your head a little to the side or whatever, the photographer will probably tell you to look straight ahead. It's just the rule. Policemen/bartenders/bouncers/etc need to be able to see a clear picture of you when they check your ID.
