Sorry it didn't make any sense to you. I was quoting from memory. I looked up the actual quote just to be sure I had it right. "How a king may go a progress through the guts of a beggar" is a crude excerpt of the following (I underlined and colored in red the part in question):
Hamlet
Act IV. Scene III
Enter Hamlet and Guildenstern.
King. Now, Hamlet, where’s Polonius?
Ham. At supper.
King. At supper! Where?
Ham. Not where he eats, but where he is eaten: a certain convocation of politic worms are e’en at him. Your worm is your only emperor for diet: we fat all creatures else to fat us, and we fat ourselves for maggots: your fat king and your lean beggar is but variable service; two dishes, but to one table: that’s the end.
King. Alas, alas!
Ham. A man may fish with the worm that hath eat of a king, and eat of the fish that hath fed of that worm.
King. What dost thou mean by this?
Ham. Nothing, but to show you how a king may go a progress through the guts of a beggar.
