Edith mentions The Hustler (1961). Vincent Gardenia (Frank) was in that movie.
Edith wonders aloud if Dear Abby writes to Ann Landers when she has a problem. In real life, Pauline Phillips (aka Dear Abby) and Eppie Lederer (aka Ann Landers) were twin sisters.
George Jefferson's second appearance. However, since George's first appearance (in "Henry's Farewell") saw him anything but friendly with Archie, and even his other appearances this season had he and Archie at odds, it seems strange to see Archie and George greet each other so friendly and civil at Kelsey's bar.
This was the second appearance of George Jefferson. It is George's only appearance in Kelsey's Bar (on-screen anyway. Next season's "Archie and George Make a Deal" starts with Archie informing the family that George was at Kelcy's buying rounds for everyone).
