The Great Kahuna

S1, E3: Twenty-eight year old Cass Cobb, known to the surfing set as the Great Kahuna, takes up with Gidget to fend off Buff, a blonde beauty who has followed him from Hawaii. Not only does her relationship with the older man fill her waking hours, but Gidget dreams of an idyllic life with him on a native island. Russ goes to the beach to meet Kahuna. To Gidget's disgust, they become friendly. Russ gets Gidget to invite Kahuna to dinner. Kahuna arrives, having completely divested himself of all traces of his unconventional way of life. Gidget is stunned when Kahuna tells of his plans to settle down to a normal, completely unromantic existence. Although Gidget feels she is the victim of a plot hatched by Russ and Kahuna, she tries to fit herself into Kahuna's plans. Before he leaves, Kahuna suggests she have a talk with her father. The next day, at the beach, Gidget reads two letters, one from Kahuna, the other from Jeff, at college. Kahuna's letter announces he is settling down with Buff in Oahu; Jeff's tells of his plans to roam the world until he is about thirty.
