The third game in the Monkey Island series, The Curse of Monkey Island was released in 1997, six years after the previous installment, LeChuck's Revenge. With two of the three fathers of the series, Ron Gilbert and Dave Grossman, no longer working for Lucas Arts, and the third, Tim Schafer, being busy with other projects, no one was really around to explain the infamous ambiguous ending of LeChuck's Revenge, so the company decided to go with a Cuckoo Nest interpretation of it.
