Seriously, Poo? You Use Poo to Get High?

Who the hell thought this up? I can understand the first person who did this, but how did he convince the second? How did that converstaion go?
"You gotta try this man, my poo gets me high!!"
Honestly, that guy needs to stop smelling his own poo and become a salesman. A guy so convincing that he makes people breathe in the gas from their own poo? He could make MILLIONS!!!
