Man With a Net

Man with A Net is the 75th episode of Gilligan's Island and the seventh episode of the third season. It aired October 24, 1966.

Synopsis
Gilligan is relaxing by the lagoon when he is accosted by a strange man with a net trying to catch a butterfly. It turns out he is Lord Beasley Waterford, a renowned but eccentric butterfly collector in pursuit of a rare butterfly called the Pussycat Swallowtail. He promises to rescue The Castaways, but as the Professor reveals, a scholar like Waterford can take weeks or even months to capture his specimen. Eager to expedite their rescue, Ginger tries to romantically cajole Beasley and Mr. Howell tries to bribe him, but he is oblivious to their attempts. The Professor even tries crib sheets to assist Beasley in his search to bond with him, but he is exposed as a fraud. Gilligan, meanwhile, reveals he has found Beasley's flare gun, which isn't loaded when they fire it. Realizing they have been trying to shorten his quest, Beasley reveals he has hidden the flares and resorts to running the Castaways ragged in search of the butterfly; Gilligan at one point casually waving it off at one point. Tired of Beasley's tyrannical requests, the Skipper and Professor resort to getting Beasley drunk to get the flares, but end up getting themselves drunk. Beasley's stout British stamina proves resistant to their island-made tea, and he casually catches the butterfly. Unfortunately, he cannot rouse the Castaways from their inebriated stupor to take them home. Two days later, Gilligan and the others wake up from their stupor to discover Beasley has left them behind. On the radio, they learn he has failed to tell anyone about them before heading off to Siberia in search of another butterfly.
