9x25 - All in the Family

Louise Jefferson returns for a visit at the Bunker's place to ask Edith if she can sell her (Louise's) former house. Edith doubts but Archie makes her agree so that they (mostly he) can choose white people to move in. When Edith sells the house to a couple and she invites the lady to her house, Archie realises that the woman is black and so is her husband. But Archie isn't disturbed when he finds out that the man is a cop, which could be good for Archie's safety.
