Second Banana

S4, E11: Lillian is approached by a producer who wants to use her diner for a "Banana Cream" cosmetics commercial because of its 50's-style décor. Charles is asked to handle the financial arrangements with the producer, Veronica Radford, so he invites her to his place, thinking it is a way to combine business with pleasure. That evening, Veronica takes note of both Jamie and Sarah and tells Charles that the sister with the "fresh fifties" look would make the perfect substitute for the model who just backed out of the commercial deal. Charles assumes that she is referring to Jamie and passes along the good news. The next day, Jamie shows up for rehearsal at the diner only to discover that the "fresh fifties" face belongs to Sarah. Director Todd Sterling detects Jamie's disappointment and offers her a dancing banana part.
