Archie has a pleasant phone conversation with his brother Fred in this episode, but when Fred appears in season 8, they say they haven't spoken in 29 years.
Archie: If God intended for white people to dance with colored people...
Michael: ...He'd have given us rhythm too.
Archie: I'm saying youse guys oughtta stick with youselves.
Lionel: You mean guys oughtta stay with guys?
Archie: You know what I'm talking about, Lionel. I'm saying that whites oughtta stay with whites and coloreds oughtta stay with coloreds.
Lionel: Look, Mr. Bunker, it's been a year and a half now since we moved into this neighborhood. I was just nineteen, and I got a big kick out of you and me for a long time. But I'm pushing 21 now, and I'm not getting that big a kick out of it anymore.
Archie: Put a lid on it, Lionel...
Lionel: I'm not finished. Now we've been friends and we can go on being friends. But when it comes to black and white and all the other wonderful thoughts you have in between, put a lid on *that*, Archie!
