Today's Stichomancy for David Letterman

The excerpt represents the core issue or deciding factor on which you must meditate, and is drawn from King Henry VI by William Shakespeare:

KING EDWARD. But master mayor, if Henry be your king, Yet Edward, at the least, is Duke of York.

MAYOR. True, my good lord; I know you for no less.

KING EDWARD. Why, and I challenge nothing but my dukedom, As being well content with that alone.

GLOSTER. [Aside.] But when the fox hath once got in his nose, He'll soon find means to make the body follow.
