Hi-Fi Gilligan

Hi-Fi Gilligan is the tenth episode of the Second season. It aired November 25, 1965.

Synopsis
The Professor is tracking a typhoon about to hit the island through the radio, and the Skipper and Gilligan are stocking supplies to ride it out in a cave. The Skipper, however, accidentally strikes Gilligan in the jaw with a crate, causing one of the fillings in his mouth to act as a receiver. This is an ideal solution for the Castaways as the Professor is using the radio. Ginger and Mary Ann use Gilligan to listen to their exercise program, but at night, the Skipper can't sleep with all the noise. Gilligan wanders The Island disturbing everyone else trying to sleep. He eventually crosses over where the Professor is trying to track the storm, stumbling and fixing his teeth but breaking the radio. Unable to track the storm, the Professor is desperate to fix the radio. Gilligan, meanwhile, offers to have the Skipper re-smack his tooth into a receiver to help the Professor, eventually smacking himself in the head and resetting the tooth. With Gilligan's tooth acting as a receiver again, the Professor realizes the storm is coming right at them and everyone takes refuge in the cave which with the supplies, but it isn't big enough to hold all of them. They draw straws to determine who will have to leave the cave. Gilligan secretly shortens his straw to spare the others, but eventually, everyone leaves the cave to stick it out with him. With everyone out of the cave, a lightening bolt strikes it, caving it in as Gilligan effectively saves their lives.

Trivia

 * Archived storm footage from the opening theme is used as the typhoon in the episode. This footage would be reused through the series and in Rescue from Gilligan's Island.
 * Gilligan seems to cause a lot of damage to the radio for just knocking it off the table; he knocks the back off and causes it to eject all of its electronics as well as a jacket for holding vaccuum tubes which would not be in a radio.
 * With all the caves seen on the island, it's odd that the Professor and Skipper chose a narrow one that obviously couldn't hold all the castaways. However, it's probable they chose this cave doe to its proximity to the camp and ability to reach it quickly over the others.
 * The syndicated version of the episode cuts the last scene where the Professor reveals the typhoon was broken up by an electrical storm, something that doesn't actually happen.
 * In May 1995, the TV Series Roseanne had a homage episode to "Gilligan's Island" where the cast played the Castaways. One of the series references they made was to Gilligan becoming a radio from this episode and the volcano from Operation: Steam Heat. The cast of "Gilligan's Island" also reunited to play the "Roseanne" characters.
