The castaways as prehistoric cave people
19 June 2016 | by kevinolzakSee all my reviews

"The Secret of Gilligan's Island" opens in a cave where the Professor identifies a prehistoric tablet of hieroglyphics created by long extinct cave people. There's some fun with a pot of acid meant to clean up the tablet, as Gilligan's attempts to sample the 'soup' are doomed to fail. More pieces are found until the Professor is close to deciphering the message contained by the entire grouping. Gilligan dreams all the castaways are cave people, Mr. Howell the fearsome but still henpecked chief who refuses to allow any of his people to escape to freedom on other side of hill. Ginger know how to persuade him, though he objects to being called Chiefy Weefy: "Chiefy Weefy Wifey get mad!" A stop motion dinosaur caps the sequence, and pretty much the whole episode.
