1x34 - Gilligan's Island

A famous painter who has renounced civilization, Dubov, visits the island (with a short-wave radio, of course). The castaways are hopeful that Dubov will give them his transmitter, but soon discover he does not wish to go back to civilization. They must come up with a scheme to make him change his mind, and attempt to make him jealous by pretending Gilligan is an artistic genius.
