Jay Johnson appears as one of the ventriloquists at the convention. Ironically, a year later, Nina Conti and her puppet, Monkey, would do on the Christopher Guest series "Family Tree" what Jay's character, Bob, and his dummy, Chuck, did on "Soap" decades earlier: On each series, both Jay and Nina play family members who think their puppet is real: all the while using it as a means to insult people i.e. to voice their true, blunt and politically-incorrect opinions and observations.
