Regular cast members Goldie Fisher and Mr. Quizzer are both absent from this episode. Recurring characters making appearances at the Open Mic Night are environmental expert Lorna Greene (who reads poetry off a piece of notebook paper she'd "recycled" over the years for grocery lists and various creative writing), sound booth technician Soundra (who is nervous about performing and feels "stuck in a box"), and MeTV cops Det. Abouttoretire and Det. Newtotheforce (who bust into the studio to arrest Bill and Toony for operating a nightclub without a license, but wind up busting some moves for the adoring audience).
