It is Joanna's forty-eighth birthday and she is thrilled to receive a locket, which she is told is from Lyndon. However it is actually from Alan and contains his semen. Meanwhile, Martin is also anxious to relay birthday greetings to his mother but has trouble getting through to her. Caroline and Angela find Guy's list of the most fanciable women on Green Wing and Caroline is annoyed to find Angela placed above her. She plans revenge but is thwarted when Mac and other male staff threaten to tell Guy all the unflattering things she has said about him. Martin finally gets to wish happy birthday to his mother - Joanna, who is rather anxious to keep her maternity secret.
