All I'm saying is that part of the information we share here has to do with the tension between subjective experience and technical data, and that in those realms where subjective experience completely departs from measurable data, humorous rebuttal can be a good antidote to pious belief, neither of which can claim a very close relationship to flat truth, but one of which does make that claim.
Burn-in, recabling, and the like are an outer fringe of audiophilia, one where our subjective evaluation cannot help but be influenced by effort and desire: we've spent money, read good reviews, and at once both want to hear a difference and are afraid not to hear one. Even those who accept that burn-in really happens and creates noticeable differences (of whom I am one) should admit that much of what is said-- not everything, but much-- about 500 or 1000 hour changes is absurd, and worse, an absurdity masquerading as "information", advice for the inexperienced and unsuspecting who are merely trying to learn what might be out there for them.
Humor has a function in discourse: it dissolves things. Criticism and cautious disagreement are a weak response to a mystical faith in sudden changes in the performance of electronic equipment with a thousand hours of logged use. Did PMS go so far as to depart from good taste and become offensive? Some of you seem to think so, but even so that would hardly be a rare occurence on head-fi. The key thing is he was kidding, making a point but not being serious about it, while the people who attacked him were generally not kidding, even when they tried to joke. And all because they felt insulted that someone was making fun of them for being (over?)excited about the burn-in of their headphones.
edit-- okay maybe the ballsack thing was a bit much
