Jack apple was the term used by British sailors in the 1800s for the apples that were kept on the ship that were kept fresh by floating in a barrel of rum. The sailors would eat the apples, and if they ate more than one a day, they would become "jack appled." As it moved onto modern times, a jack apple became slang for a dottering fool.
