It is in the irony of the jackass fly. And their uncanny attraction to high value goods. Spending their life long day proclaiming via their load and continuous buzzing (to all, who can't help but listen or at least witnes the virtual swarm) "this is a manure pile, that's why I'm here"!
But the jackass fly, while appearing to come ever so close never actually partakes of the manure! Instead at the last moment swerves off professing the stench too great with the very speed ferocity of its recoil. What possibly could explain such a profitless vigil? There has to be a higher power, a for profit higher power making up to the jackass fly for its profitless efforts. Yes, I'm a believer in higher powers, these are unmistakable a signs. Give it up for the jackass flies and their higher powers, sell low and buy high!
