As a follow-on from the preceding post:
Sanford and Son was hailed by millions as America's first "real" black sitcom.
Prior to its arrival on the scene, there had been black sitcoms but the problem (for black audiences) was that the black characters tended to speak like white people.
Sanford and Son changed that and the show was a hit with Americans of all ethnicities.
The series was enjoyed by all ethnicities but it was absolutely adored by black Americans, mainly due to killer jokes like this in the first five minutes of episode 1.
The son wants to better himself and is telling Sanford he fancies trying his hand at ship-building.
SON: With what I know about iron and steel I could be a millionaire, just like that Greek cat that married Jackie Kennedy. And you know something? He started out poor - just like me.
SANFORD: Only one difference.
SON: What's that?
SANFORD: He started out a Greek.
And with that simple line, 20-odd million black Americans realised they were at long last watching people on TV who spoke their language - in every sense!
