Since he was in the studio, Richard asked Benjy if he'd substitute for Sal and "blow air in his ass" through a straw, which Benjy agreed to. After Richard got naked and inserted the straw, Benjy announced he got a whiff of "a real assy smell" but proceeded to blow the air anyway, which immediately caused Richard to let it back out.
Benjy continued to blow more air into Richard, and Richard described that he felt like there was "a bubble" in his rear end. As Richard tried to expel "the bubble," he acknowledged he had to stop because he was afraid more than just air would come out.
Following a third attempt, Richard removed the straw and Will disgustedly announced "the straw was brown."
This led Benjy to yell to Richard, "You had sh*t in your ass," to which Howard replied, "What did you think you were smelling?"
While Howard tried to change the subject, Gary got on his intercom to say Richard was in the hall throwing up. Howard then got a microphone on Richard, who admitted he got sick when he looked at the stained straw that had been in his rear end.
