"Little Island, Big Gun" is the very first episode in which someone arrives by boat, featuring Larry Storch as Jackson Farrell, small time crook on the lam after knocking over the Monarch Bank, his loot in a little bag that Gilligan unwittingly shoots out of a tree. Introducing himself as a doctor destined to use the cash to build a hospital on a nearby island, Farrell admits to Gilligan how generous people were in making donations: "you should have seen the way they handed it over to me!" He delights in revealing his specialty to be surgery: "I've devoted most of my life to removing things!" A radio announcement broadcasts Farrell's true identity, after which he wastes no time in holding everyone at bay with his loaded pistol. The unexpected arrival of the Indigo Mob forces the castaways to dress up as savage natives, or else risk Mary Ann's life should Farrell be displeased. From Mr. Howell's cries of 'moola moola moola' to Ginger's slap in the face, the islanders are a real hoot fooling the rival gang (played by Louis Quinn and Jack Sheldon). When Jackson's henchman Gates (K.L. Smith) returns to pick up his boss, Gilligan tosses them the anchor, which sinks to the bottom of the lagoon with the now shredded money, Farrell now anxious to get away: "with Gilligan on that island you can't win!" It's nice to know that Gilligan's incompetence comes in handy when he and his fellow castaways are in danger. This was the sole episode directed by longtime actor Abner Biberman, whose numerous TV credits behind the camera (over 100) dwarfed his on screen appearances.
