Alan Hale Jr., who played the Skipper on Gilligan’s Island, was born March 8, 1921. He died in 1990.
The Skipper’s seldom-mentioned name was Jonas Grumby. Below see Hale as the Skipper as Polonius performing “Neither a Borrower Nor a Lender Be” in a musical production of Hamlet staged by the castaways. (That’s Mary Ann in boy drag as Laertes.)
