Nyet, Nyet, Not Yet

Nyet, Nyet, Not Yet is the 45th Episode in the series and Ninth episode in the Second season. It first aired on November 18, 1965.

Synopsis
The Castaways discover two Russian Cosmonauts named Igor and Ivan have crashed on the island. They see their crash as a chance to be rescued, but there's a lot of mistrust between them. The Professor doesn't trust their arrival as random, and Igor and Ivan don't believe their claims of being stranded. Using a ruse, the Professor takes Gilligan to sneak on their craft to use a radio, but Gilligan hangs on a power switch and short-circuits their radio. Although they're caught, the Professor is the only one who can fix the radio so that the Cosmonauts can call for help. Gilligan, meanwhile, overhears them planning on leaving everyone behind after drinks. Without anyone capable of handling the Russian vodka, Gilligan has to sneak aboard and replace one marked bottle of Vodka with water. The men thereby are able to drink the Cosmonauts into submission, and leave them to be disgraced by their countrymen, but the next morning, Gilligan sets his watch to Manila time, and everyone misses the rescue boat. A few days later, the Castaways learn from the radio that the Russian Space Program has relocated their misplaced capsule to the Black Sea to cover-up their accident.

Trivia

 * The syndicated version of his episode cuts out the ending where the Skipper and Gilligan hear of the rescue of the Cosmonauts.
 * The footage shows the Russian capsule coming down like a falling star when it should have descended on a parachute.
 * The tea urn and framed photo of Lenin in the Russian capsule shouldn't have survived traveling into space or even re-entry.
 * In a previous episode, the Professor claims he speaks several languages. However, in this episode, it seems Russian is not one of them.
 * There is no Russian tradition of switching drinks before a toast.
 * The coconut cups actually "clink" when struck, suggesting they are made of something other than coconut.
 * Since English is their second language, it's odd that Igor and Ivan plot against the Castaways in English where someone could hear them rather than their native Russian.
 * Mr. Howell mentions his brother-in-law in this episode; he also mentions him in Seer Gilligan.
