The phrase comes from Gilligan's Island, the American sitcom that aired on CBS from 1964 to 1967 about seven castaways stranded after a shipwreck. Gilligan, played by Bob Denver, was the accident prone first mate, and the Skipper, played by Alan Hale Jr., frequently called out to him before a plan went wrong. Clips of the greeting later circulated on soundboards and in edit culture, where the old TV call became a shorthand for spotting a lovable troublemaker.
