Trivia

 * In the syndicated TVLand version, the ending is cut out which shows the Professor revealing to the Skipper and Gilligan the spy's gold pocket knife. Although ruined, it had over 200 different uses: radio/transmitter, tape recorder, laser beam and even a death ray! The Skipper is in shock when he realizes Gilligan was telling the truth of another Gilligan on the Island!
 * The Spy finds it easy to imitate Gilligan - just say the first dumb thing that comes to mind. The spy also claims Gilligan is so inept that he wouldn't even be a spy 3rd class
 * The part of the twin spy was played by Bob Denver.
