T1, E4: Professor Russell Lawrence complains that surfing has become an obsession with Gidget. Pointing to his involvement in his professional duties, Gidget persuades her father to spend time at the beach with her. There Russ meets Sally Combs, an attractive woman in her mid-thirties. Gidget becomes alarmed by her father's interest in Sally, especially when Larue refers to Sally as a gold digger. When Russ takes Sally to dinner, Gidget gets really worried. Her efforts to arouse Anne and John fail, particularly when John, echoing her father, says that she is projecting herself into a mother role. At a late hour, when Russ doesn't return, Gidget, imagination working overtime, decides he has met with an accident. Gidget phones the police. Officer Joe Hanley locates Sally and Russ and is nonplussed when he discovers Russ' age. He tells Russ his mother wants him. Russ arrives home, furiously decrying the fact that he believed he could treat Gidget as an adult. He relents when Gidget makes him understand that she was genuinely concerned about his wellbeing. Gidget concludes that the world's problems arise because there is some adult in every child and some child in every adult.
