It's in the episode on March 29, 2005, "Tom Gives Voice To The Disenfranchised. An Actor Playing Tom In Philly Boy Roy's Movie Calls. And Someone From The Band 'Crust' Checks In, Trying To Start A 'Crust Space'."
I am not sure where it is in the episode but Wurster is reciting PBR's script with that line included.
