Please Sir! - Season 3 (1970)

It's career day at Fenn Street School and Mr Hedges gives a demonstration on how to behave in an interview.

Mr Smith collapses in the street and is rescued by Peter, Maureen and Frankie. Dennis is given a black eye by his father, and Mr Hedges finds a new home.

Mr Hedges fears that Maureen has run off to join a convent.

After losing the cross country run to the rival Weaver Street School, 5c decide they will make amends by helping Mr Hedges win his golf match against Weaver Street's Mr Kelp.

Miss Ewell hears some upsetting news and Mr Cromwell sees his chance to win her back. Meanwhile, Mr Potter's elicits the help of 5c with a length of carpet that should be in the headmaster's study.

As part of 5c's political education, Mr Hedges arranges a trip to the local Conservative club. However, Maureen's behaviour continues to spin out of control.

Norman potter is chosen to be the face of a national advertising campaign for beer, much to the disapproval of the Chair of Governors of the School.

Mr Hedges is thrown into a moral quandary when Frankie Abbott reveals his ideas on reproduction. Meanwhile Mr Potter offers to help decorate Bernard and Penny's new home.

Mr Hedges is growing increasingly worried about Dennis' lack of a job when he leaves school. One possibility is working as a stable boy at the local brewery, but will Dennis' father allow it?

It's the last day at school for 5c and Mr Hedges try's to play it cool and not show his emotions.

Christmas special. Bernard and Penny are getting married today. They predict that everyone will interfere with their plans to stay at the hotel, so they tell everyone they are going to Portugal for their honeymoon. When they sneak back to the hotel, they get a surprise.
