The truth about Jack's signature walk
All of us know that Captain Jack Sparrow's drinking choice isn't water exactly, but the reason the way he walks is actually not related to his drinking habits as a character. He develops the ability to walk steadily on the deck of a ship, but at the same time, he is less steady while walking on the land. You may assume his signature walk results from his being constantly inebriated, whereas the truth is that he has sea legs.
