Quick Before It Sinks

Quick Before It Sinks is the Sixth episode of the Second Season. It aired October 28, 1965.

Synopsis
As Gilligan collects the lobster traps from the lagoon, the Professor appears at the water's edge and points out a measuring stick to the Skipper he has been using to mark the tide. Seeing as it is almost entirely under water, he concludes the island may be sinking into the ocean. They choose not to worry the women with the news, but when Gilligan thinks wearing stilts as the answer, the Professor believes building new huts on higher ground may be the answer. However, building them in secret at night proves to be a challenge as Mrs. Howell and the girls want to landscape the hut area. At night, the men are trying to build a new hut at night, only to stumble back exhausted at dawn only for Mary Ann to "wake" then to start working again. Meanwhile, the Professor checks his measuring stick in the Lagoon and discovers it's now completely submerged and the island may be sinking faster than he believed. They now realize they have but no choice to tell the women the truth, and Gilligan is forcibly drafted to tell them. However, Ginger misunderstands his awkward confession and thinks they're being rescued. The Skipper and Professor are astounded as to how Gilligan screwed up telling her, but Gilligan joyfully watches from afar as Ginger rushes up to them and has them confirm the news without telling the truth. The Professor fakes a transmitter with Gilligan disguising his voice as their contact, but after Ginger steps on Gilligan's foot, the deception is exposed. Hearing the truth, Mary Ann thinks they should build a large ark for them ride out the rising water. The Professor also goes on to build a huge rope and pulley assembly to test the rocking of the craft on the ocean. On board, Gilligan and the Skipper live through the turmoil and disaster of extremely high tides rocking them back and forth and sliding the furniture around before finally collapsing on top of them. As the Skipper and Professor are trying to decide what to do next, Gilligan checks the lobster traps and comes back carrying the Professor's measuring stick. It turns out he's been moving the stick into deeper water to catch bigger lobsters, rendering all their hard work a waste of time. Since the island isn't really sinking, Gilligan gets stuck cleaning the mess by himself as punishment for starting the panic.

Trivia

 * One of the more sillier funny episodes; Mr. Howell actually has to do physical labor, Gilligan and the Skipper testing out the hut/raft which collapses and Gilligan revealing that was he who had changed the stick in the water for his lobster traps.
 * The Professor shows extremely poor geological knowledge by not noticing the stick he was using was actually being moved.
 * In Rescue from Gilligan's Island, the castaways do make a hut/raft to survive a storm and end up inadvertently escaping the Island.
