The Invasion

The Invasion is the 79th episode of Gilligan's Island and the eleventh episode of the third season. It aired November 21, 1966.

Synopsis
While fishing in the the lagoon, Gilligan pulls in a military briefcase that incites the curiosity of the Castaways trying to look inside it. They try various stunts to take the case and peek inside, but the Professor foils each of them. The following morning, the case has vanished, having been passed one by one covertly through the Castaways trying to hide it until Gilligan gives it back to the Professor, who pounds it in disgust only to discover it has secret military papers in it. Gilligan hand-cuffs himself to it to protect it, but the Skipper realizes Gilligan would be killed when the men after the case find him with it. That night, Gilligan has a dream he's a secret agent, and everyone is a spy trying to get the briefcase with Mr. Howell as the head of the evil organization after it. When Gilligan wakes from a start after the dream, Mr. Howell comes running and scares him, opening the case and revealing the key to the cuffs. The files, however, turn out to be from World War One, which means no one would be after them after all. Deciding to toss the briefcase back into the lagoon, Gilligan tells the Skipper and Professor about his dream, adding that the Skipper was an imposter of his mother and the Professor was the head of the good guys and that the briefcase was rigged to explode. Upon tossing it, it really does explode, surprising them.

Trivia

 * The syndicated versions of this episode delete the tag scene where Gilligan remarks on the briefcase self-destructing and the resulting explosion.
 * Mr. Howell's hollow log disguise is possibly the same one Gilligan wore in Two on a Raft.
 * During the dream sequence, Ginger says, "Sorry about that, Chief," which was a known catch phrase of character Maxwell Smart on the TV series, "Get Smart." Coincidentally, she mentions another of his catch phrases, "Would you believe..." in Splashdown.
 * In Gilligan's dream, the Professor is Gilligan's superior, Mr. Howell is the head of EVIL, a covert espionage agency, and Mrs. Howell, the Skipper, Ginger and Mary Ann are EVIL agents.
 * As the villain in Gilligan's dream, Mr. Howell has a bald head, perhaps harkening to criminal mastermind Ernst Blofield in the James Bond film franchise.
 * This is the first episode where Alan Hale Jr. appears in drag, the others being Lovey's Secret Admirer and Gilligan the Goddess. Russell Johnson was enormously amused by him in costume, comparing him to Jonathan Winters as the character "Maudie Frickert."
 * Gilligan also describes his dreams to the others in And Then There Were None and The Secret of Gilligan's Island.

 * Gilligan - "Professor, Open it, open it, open it!"

Skipper - "No, Mary Ann... I'm afraid I've already had a dozen." Ginger - "Eat another dozen and walk them off." Gilligan - "If he eats another dozen, he can fly them off."
 * Mary Ann - "More sea gull eggs, Skipper?"

Gilligan - "It's okay if you want to hide it, Professor, it is your turn."
 * Professor - "Now, do you all want I'm going to do with this case?"

Head Good Guy - "I didn't know Beethoven was a secret agent!" Agent 014 - "You see how good he was."
 * Agent 014 - "You're talking to the greatest secret agent since Beethoven."

Agent 10 - "Of course, the steak is covered in arsenic, and the sauterne is filled with arsenic." Boss Howell - "Oh, ghastly, no! No!" Agent 10 - "Do you object to poisoning him?" Boss Howell - "No, I object to white wine being served with meat."
 * Boss Howell - "Good Guy 014 is on his way to see you. You have plans to dispose of him I hope, of course."


 * Mrs. Howell - "Now I know why you're called 014; you're twice as good as 007!"
