Walk the plank

"Walk the plank!" "What did the bird say?!"

- Cotton's parrot and Jack Sparrow

Walk the plank was a term used, most notably by pirates, to force a person to walk to one's death by stepping off a plank extending from the ship's side over the water. Jack Sparrow and Elizabeth Swann were forced to walk the plank by Hector Barbossa aboard the Black Pearl. The infamous undead captain Jolly Roger is known to make pirates walk the plank.
