On the Buses S02 E03 Self Defence

Several bus crew staff have been attacked every Saturday night by drunken yobs who rip their advertisements, steal parts and spray paint obscene graffiti on the sides of the buses. When Stan and Jack are the victims of the worst attack yet, with Stan getting his trousers ripped and being unable to pick up the fish and chips for supper, they refuse to work on Saturday nights. Blakey advertises a self-defence class, teaching martial arts, as an alternate solution. The pair are reluctant to join but soon change their minds, chiefly because two attractive conductresses are also in the class. Inevitably the two men get thrown around by the women, much to Blakey's amusement, but they get the last laugh when they discover that Blakey is no woose either.
