Stanley Adams guest stars as King Killiwani, a native chieftan who comes to the island in search of a White Goddess. Naturally, the female Castaways are thrilled at the prospect of being chosen for this honor. But when it turns out that the White Goddess is slated to be sacrificed to a volcano, Gilligan (Bob Denver) "courageously" dolls himself up in female drag to offer himself to the persistent Killiwani. Although no one--not the cast, not the producer, not the network--knew it at the time, this turned out to be the last half-hour episode of Gilligan's Island.
