"George W. Bush. To the untrained eye his pursed sneer and heaving shoulders suggest a man who is certain of his place in the world, a man of profound self-awareness and in full possession of a breadth of knowledge that would make his fellow statesman pale. But the tragic reality is that his colon is a virtual snake-pit of methane, and woe to him that treads too close to its edge as the poor unfortunate will be overcome and likely tumble ass over kettle into the caustic, writhing fog. As Bush strains to restrain, the temperature of the aforementioned vapor increases and his efforts to prevent its escape duly correspond. As water in a corroded sewer pipe always seeks an alternative route should its main artery be clogged, so the fumes push and propel themselves to other vacant areas, most notably to the cranial region, propelling our distressed leader to perform a series of ever inexplicable actions. How else to explain the last 7 years of bizarre behavior both within and without the Rotunda? And all because of the hateful hellion Flatulence."
