Gilligan's Island

Lord Beasley Waterford, a famous butterfly collector, lands on the island searching for the world's rarest butterfly, the pussycat swallowtail. While he vows that he will not leave the island until he has found his prey, the castaways eagerly try everything to persuade him to fire his flare gun early. He (like all of the other visitors to the island) leaves without sending help.
