Physical Fatness

Physical Fatness is the 32nd episode of the First Season. It aired May 8, 1965.

Synopsis
The Professor has found a way to create a phosphorus dye that will glow at night and may get the Castaways. When Gilligan learns this, he runs to tell the Skipper the good news then changes the subject as to what they will do when they're rescued. With the S.S. Minnow out of commission, the Skipper feels he has no recourse but to re-join the U.S. Navy. However, when he checks the Navy Regulations handbook for his required weight, he realizes that he's twenty-two pounds overweight and needs to lose weight. He asks Gilligan to help him lose the weight, and one night while sneaking out for a snack, Gilligan is found hiding in the food locker. During the day as Gilligan is working on the raft, Ginger helps the Skipper exercise, and Mrs. Howell gives him a bottle of diet pills. Gilligan then discovers that at 125 pounds he is five pounds underweight to join the Skipper in the Navy. Mary Ann and Ginger are now trying to fatten up Gilligan to help him, which irks the Skipper who has to watch Gilligan eat as he works on the raft. Eventually, the raft gets done, and the Professor leaves his dye near Gilligan to help the Skipper get it into the water. Gilligan unfortunately mistakes the dye for food and starts eating it, and at dusk, the Skipper calls Gilligan to bring the dye. Ginger is first to notice Gilligan's spectral form glowing in the dark as he arrives on the beach with the empty bowl. As punishment, the Skipper sticks Gilligan atop the lookout tower, rotating around and around with a blanket and imitating a signal light.

Trivia

 * When the Skipper stands on the scale in the Supply Hut to check his weight, the Professor warns him the scale goes only up to 200 pounds. Likewise, Gilligan warns him after he sits on the Fish Scale that the Skipper weighs between a largemouth bass and a hammerhead shark!
 * It is unknown as to how old the Skipper's Navy Regulations book is; chances are the regulations might have changed in the interim. It is also likely he could rejoin at the same pay grade he was when he left the Navy.
 * When they weigh themselves, the Skipper weighs 221 Pounds, 22 pounds over the Navy limit, and Gilligan weighs 125 pounds, 5 pounds underweight.
 * The Skipper shouldn't have to join the Navy after getting rescued as his insurance company would reimburse him the cost of the Minnow, as revealed in Court-Martial and Rescue from Gilligan's Island. Failing that, Mr. Howell would surely buy him a boat.
 * Gilligan would likely have experienced serious if not fatal side effects from drinking a phosphorescent dye.
 * In President Gilligan, Gilligan suggests they build a lookout tower; in this episode a tower has been built.
