Third time Maxwell and the Nanny kiss.
Jack Walker (J.D. Daniels) is the star of the fictitious sitcom 'Royal Flush' which, according to Fran, "beats 'Full House (1987)' every time". Daniels appeared in 'Full House (1987)'.
At one point during the episode, a disgusted Fran refers to Jack as Damien. This is a reference to The Omen (1976) in which the Antichrist in the form of a young boy is named Damien.
The title is based on the Disney song 'When You Wish Upon A Star'.
