ON THE BUSES (1969) Series Two Ep 3: Self Defence
Jack and Stan are amongst bus crew staff who have been attacked by drunken yobs and, when Blakey advertises a self-defence class, teaching martial arts, the pair decide to join - chiefly because two attractive conductresses are also in the class. Inevitably the two men get thrown around by the women and discover that Blakey is no slouch either.
