Pardon The Expression (Season 2 - Ep.4) Self Defence (1966)

First broadcast: 31st January 1966

Plot (From Corriepedia):
Every time Mr Swindley goes to the bank he is taking his life in his hands. The answer, he decides, lies with judo. But when Mr Swindley makes trouble for everyone including the Rev. Lloyd who is visiting the store to collect donations and overhears Swindley and Mrs Edgeley attempting throws with one another in the storeroom and leaps to the wrong conclusion as to what all the talk of hands on waists and legs is about. Mr Swindley decides on professional coaching and enrolls with Gerry's Gym. He provokes Mr Hunt into joining him but a mistake in picking up a discarded black belt for his Judogi means that the students in the class think he is the real thing and attack him eagerly. Painfully sore the next day, Hunt is again visited by the vicar who reveals he is also a black belt. The reverend gentleman is aware of the mistake he made when he overheard Swindley and wishes to apologise. A vengeful Hunt sends him after Swindley who has just set off for the bank. The two men end up in hospital when Swindley mistakes the vicar's friendly tap on the shoulder as the prelude to an attack and defends himself thoroughly...
