Synopsis by Hal Erickson
Harold J. Stone guest stars as Alexi Gregor Dubov, an eccentric painter who has arrived on the island to escape civilization. It turns out that Dubov has a short-wave radio transmitter--but he has no intention of using it to help the castaways get of the island. In an effort to force Dubov to contact the mainland, the castaways devise a devastating blow to the painter's ego by convincing him that goofy Gilligan (Bob Denver) is an artistic genius.
