Ah, I forgot to explain a quirk of mine.
While using a knife at the dinner table, I tend to use the fork with my left, and knife with my right. I can't do that without fumbling with the fork though...
While handling a hand gun, I'll fire with my right. While handling a rifle however, I will pull the trigger with my left. That is only because my left eye is a hell of a lot better than my right. I have actually managed to create scripts for Counter Strike to reflect this. I don't fire guns that much, so I don't have a chance to confuse people too much.
