 Graeme and Tim are hungry, and want their dinner — however, there is only soggy lettuce and potato peel to eat because Bill has fed their normal food (and wine) to "Bunter", a guinea pig, with dessert to follow.When Bill explains to Tim and Graeme that he is being paid £30 to look after the guinea pig, and the thought of being able to get some extra money leads to the Goodies setting up the office as the "Goodies Animal Clinic" for "loony animals".Graeme sends Tim and Bill out to collect them from their owners.
