Make .(1959) Arthur Askey, Sid James, and Bernard Cribbins

Arthur Ashton (a parody of Arthur Askey) is a makeup man working for National Television (a parody of the BBC). During a visit to the local launderette, he meets Sid Gibson, a shady pedlar who is trying to flog Bonko, a brand of washing powder in the shape of a pill. The man cannot afford to advertise on TV, but wishes to do so. The fairly clueless Arthur agrees to help him, and they manage to plug an advert for Bonko on National Television by interrupting the live feed. This causes quite a stir amongst the national television heads, who have Arthur fired. However, the advert proves extremely popular and demand for the product soars.
