When Jeannie and Major Nelson are visiting an art gallery, Jeannie runs up to a painting (never shown to the TV audience) and delightedly announces that it is "an original Ansara." This is a reference to Michael Ansara, the then husband of Barbara Eden. Ansara played the Blue Djinn in Happy Anniversary (1966), King Kamehameha in Battle of Waikiki (1968) and Major Biff Jellico in My Sister, the Home Wrecker (1969) and directed One Jeannie Beats Four of a Kind (1970).
The 18-inch Jeannie doll seen in this installment was licensed merchandise manufactured by Libby-Marjorette in 1966. It has since become a high-priced collectible.
While at the museum there is a painting of a bowl of fruit. This was painted by Barbara Edens then husband Micheal Ansara.
Butch Patrick (Richard) and Kimberly Beck (Gina) previously appeared together in an episode of The Munsters entitled "Lily Munster - Girl Model" (1965).
Richard is played by Butch Patrick, who is best known for his role as Eddie Munster in "The Munsters" (1964-1966).
