When you look your self in the mirror and say to yourself, "Well, its time for a new player model"
When you want to put your glasses on and then press F9
When you think you can undo ANYTHING
When you search for ammo in your desk.
When you try moving back, front, left and down thinking you'll activate a special move.
When you try to find your console, and actually find it. And then type in GOD and GHOST thinking now you can rob a bank instead of farming to get gold.
When you try to use scripts and blow up the server while in a difficult situation.
When you press TAB to find your frag count and score.
When you play Pacman.
