When 'Willard' is dragged out of the singles bar by his 'wife', she says "Every Friday night the same thing" and Jeannie II notes there are "2 days down, 12 more to go." In the next scene, Jeannie II tells Jeannie to "keep your Friday night open" for a double date. On the night of their double date Jeannie II tells her sister she only has 9 more days to find a new master even though a full week should have passed since the previous night out.
When Jeannie and her sister meet their dates for the evening they glance at each other and the face of Barbara Eden's stand-in playing Jeannie II is briefly visible.
