Little known fact: the practice of tangential structural urination (or TSU, pronounced “tissue”), and the related Biblical phrase, was introduced through a variant copy of the Tanakh, one that passed through the hands of a Turkish Sufi translator who moonlighted as a stand-up comic every second Wednesday (and was also a proto-Freemason — as are all stand-up comics). As Tyler pointed out in one of the Fight Club PSAs, urine is sterile; and when combined with architectural targeting and the practice of Sufi “whirling,” this sufficed as a personal/locational purification ritual.
Of course, it did require a bit of training, especially if performed in a cavernous structure or when the purification of an entire village was intended. This training has a cultural survival in the practice of “shaking,” a technique known to all (ok, almost all) young boys via the rite of passage colloquially known as toilet training; it has also surfaced in other forms, from time to time, albeit somewhat camouflaged. Two notable examples are those of Gallagher’s “Smash-O-Matic” and the antics of the Blue Man Group.
This preacher was, without a doubt, privy to this secret knowledge. (Surely one noted the numerological references? This belies a familiarity with Iamblichus’ Theology of Arithmetic, and the Neoplatonism of Proclus.) Therefore: woe, ultimate and eternal woe, will befall the ridiculers on The Day of the Divine Flow.
