The classic American sitcom Sanford and Son was actually based on a British classic called Steptoe and Son.
Much like its American counterpart, Steptoe and Son followed the hi jinks of a father/son scrap business in which a "dirty old man" tries to keep the family business afloat while dealing with his pretentious son who seeks to elevate himself above a junk yard job.
Of course, the legendary Redd Foxx took on the role of the father in the American version and made it his own. Nobody could have done it any better.
