I remember watching these documentaries in awe; they were hysterically funny and absolutely summed up a certain time and place.
Four young Herberts from Canning Town are what used to be known as knockers. Selling shoddy household goods to bored housewives on the pretext of raising money for charity. The first of these documentaries saw the knockers shamelessly playing up for the camera. The faked tear up between a rival firm is both unconvincing and hilarious.
