Gunn's ineptitude as a geography teacher gets him replaced by blind but hip Dr Dalton, Meanwhile Keith gets Sarah a birthday present, a huge photograph of Blackpool tower which believed was of the Eiffel tower. Keith and Gunn visit Sarah to help her hang the picture - which they do eventually - but stay around to witness Sarah's date with Dr Dalton, who somewhat disgraces himself and consequently resigns from the school.—don @ minifie-1
