"Oh my, Floyd just inhaled from the anus of Jay without even coughing, he's a damn good experienced anus inhaler. We shall see how Jay does tomorrow, he is much more experienced, probably has fully coated his lungs in poo by now, I bet he doesn't even taste the farts anymore, he's goin straight for the corn layer next."
