I often drink while playing Halo. My rank in Team Slayer typically holds steady for a while, but eventually drops by about 5 or 6 rankings before I'm too drunk to do anything but viciously curse at the children on xbox live.
And like the guy above me said, I don't FEEL like I'm playing worse as the evening goes on... but, uh... the numbers do not lie.
