By hook or by crook

By any means possible, in one way or another. For example, The car broke down, but I'll get there by hook or crook. This term has a disputed origin. A widely held theory is that it comes from the custom of allowing commoners to take as much wood from royal forests as they could reach with a shepherd's crook and cut down with a billhook. [1300s] Also see the synonym by any means.
