Radio Times review
Sharing is not a concept the teaching staff understand at Greybridge School. So Trevor's not happy when caretaker Gareth, who's sleeping in the classrooms, moves in with him - and then makes moves on his mother Rita (Michele Dotrice). It changes Gareth so much - "The voices in my head have gone, I'm not drinking from puddles any more" - that he even thinks he's ready to be a geography teacher again.
Also sharing (although a classroom rather than a bed) is Miss Postern and Mr Church. It's not the most sparkling end to the series, although the moment Catherine Tate's nose collides with a car window is a real gem of slapstick comedy.
