Begging to differ . . .

All of that's true Mark, however you should always keep in mind that playing "it" can be an exercise in perspective. What I mean by this is that your presumption of "it" can be rebutted - even retroactively - by a calling of "anti-quitsies" before making all the other requisite proclamations. From an "it" standpoint (especially from the perspective of your adversary) this would serve to make you practically bulletproof. I am aware of other theories out there, however as I've always been more of a bricks & mortar guy than a theoritician, this seems to be the best "real world" strategy.
