In flashbacks, Val and Fran discuss how they will con Sylvia into letting Fran go to the kibbutz by claiming they want to connect with "the ancient [Jewish] heritage of our people". However, numerous episodes of the series firmly establish that Val is Italian and Roman Catholic, not Jewish, and thus has no ancient Jewish heritage to connect with.
Fran notes that "J.J. Walker" will be performing on her parents' dinner theatre tour. The actor's name is Jimmie Walker, J.J. was the character he played on "Good Times".
