This episode is one of the reasons that Demond Wilson got the role of Lamont Sanford on "Sanford and Son" (1972). The role had been offered to Cleavon Little, who also appears in this episode, but he turned it down and suggested Wilson for the role.
Ironically, Cleavon Little would go on and briefly star in a short lived All in the Family- related spin-off Mr Dugan in 1979 (in which the project was cancelled; the three taped episodes never having aired).
