After losing his arm yet again Worzel is sick of people like John Peters calling him stupid, so he sets about the arduous task of locating his ‘clever head’. After searching high and low Worzel finally remembers where he’s hidden it - in the chimney of the local school that John and Sue go to. Worzel gets on the school roof and puts on his clever head. However, getting down is not so easy and he soon begins to draw attention to himself by making a racket. Miss Jamieson, the school teacher is so bothered by this noise that she goes out to investigate. When she sees Worzel she asks him what he’s doing on the roof and Worzel, feeling cocky in his clever head, demands a ‘satisfactory question’. The school teacher fires difficult questions at him, and to her amazement he gets them all right. She decides to tell Mr. Foster, the headmaster, that she has discovered a ‘genius’ on the school roof.
