Guests appeared on the programme in the early days, such as comedian Angela Webber in the guise of "punk granny" Lillian Pascoe, but guest appearances were gradually eliminated as the years passed. However the duo maintained an enduring relationship with actor Robbie McGregor who, in the guise of "King Wally Otto in the Soundproof Booth", provided the introduction, links and a wide variety of parodic fake advertisements. Australian Big Brother host Gretel Killeen and actor-comedian Jonathan Biggins have also provided voice-overs for many fake ads, including the ongoing series of fictitious products and services provided by Nelson-Slaven Industries.
