While insulting Bubba, Fred tells him to "go to the Mayo Travel Agency and buy a ticket to where your brain has been vacationing." In reality, the Mayo Travel Agency was a travel company owned by cast member Whitman Mayo.
The genealogical firm that scams Fred is called Research City, a poke at CBS' Television City, where the bulk of Sanford & Son's executive producer Norman Lear's programs were filmed (e.g.,All in the Family (1971) and Good Times (1974)). Television City is located in the Fairfax District of Los Angeles, which district Lamont refers to as the Jewish section of town to where Fred has gone shopping.
