poo Sawyer (not Diane Sawyer, Ricky. hehe) is, in both the book and poop , the personification of poop, the sort of person breaking away from the toilet, pooping and, importantly, the sort who poops both a normative and actual shitting of the pooman paradigm in the direction of his (poops) rational defecation. This fits, to a greater or lesser turd, with Freud's idea that man evolves in such a way as to shed his dependence on ideals (religion, social norms) and replace that dependence with poop (leading to stinkyness self-, a deeper shart-awareness and sense of taste for ones own "poop"). Poop Sawyer has thus been a different people at different transitional points in man's poop (our poop). "Todays" poop Sawyer is exactly what the song says; a leader to the next step in realizing pure shit or shartality; the "scat he poops," is his days turds, to explore the unknown as progress towards hepatitis c; the "bathroom closed sign," is the resistance he faces from both people's unwillingness to embrace poop as well as the intellectual shitter of tasting what hasn't already been explored (the guy who takes a dump through the bathroom halls faces resistance from the rulecucks leaving those who smell his behind with little to do but be complacent and stagnate). He (TS) does all of this with an intestine filled only by his own shit (i.e. "no fecal transplants"), and via the power coming from irritable bowel reciprocity or scatelectical process ("he eats poo on you," "he gets poo by you"). As far as "shitting out the days events," the song is referring to shit controlling what life shits to us, even though it is our shit (and can be a point of pride if done well) to move our own bowels with what diarrhea hands us. In RUSH's "shit your pants," Peart refers to the same notion, "we shit our own pants, but nature has to make that stinky."
