+$data = <<<QUOTE
+To be or not to be, that is the question;
+Whether 'tis nobler in the mind to suffer
+The Slings and Arrows of outrageous Fortune
+Or to take arms against a sea of troubles,
+And by opposing, end them. To die, to sleep;
+No more; and by a sleep to say we end
+The heart-ache and the thousand natural shocks
+That flesh is heir to  'tis a consummation
+Devoutly to be wish'd. To die, to sleep;
+To sleep, perchance to dream. Ay, there's the rub,
+For in that sleep of death what dreams may come,
+When we have shuffled off this mortal coil,
+Must give us pause. There's the respect
+That makes calamity of so long life,
+For who would bear the whips and scorns of time,
+Th'oppressor's wrong, the proud man's contumely,
+The pangs of dispriz'd love, the law's delay,
+The insolence of office, and the spurns
+That patient merit of th'unworthy takes,
+When he himself might his quietus make
+With a bare bodkin? who would fardels bear,
+To grunt and sweat under a weary life,
+But that the dread of something after death,
+The undiscovered country from whose bourn
+No traveller returns, puzzles the will,
+And makes us rather bear those ills we have
+Than fly to others that we know not of?
+Thus conscience does make cowards of us all,
+And thus the native hue of resolution
+Is sicklied o'er with the pale cast of thought,
+And enterprises of great pitch and moment
+With this regard their currents turn away,
+And lose the name of action.
+
+
+Hath not a Jew eyes? Hath not a Jew hands, organs, dimensions, 
+senses, affections, passions; fed with the same food, hurt with 
+the same weapons, subject to the same diseases, heal'd by 
+the same means, warm'd and cool'd by the same winter and summer 
+as a Christian is? If you prick us, do we not bleed? If you 
+tickle us, do we not laugh? If you poison us, do we not die? 
+And if you wrong us, shall we not revenge? If we are like you 
+in the rest, we will resemble you in that. If a Jew wrong a 
+Christian, what is his humility? Revenge. If a Christian wrong 
+a Jew, what should his sufferance be by Christian example? Why, 
+revenge. The villainy you teach me, I will execute, and it 
+shall go hard but I will better the instruction.
+
+Is this a dagger which I see before me,
+The handle toward my hand? Come, let me clutch thee.
+I have thee not, and yet I see thee still.
+Art thou not, fatal vision, sensible
+To feeling as to sight? or art thou but
+A dagger of the mind, a false creation,
+Proceeding from the heat-oppress'd brain?
+I see thee yet, in form as palpable
+As this which now I draw.
+Thou marshall'st me the way that I was going;
+And such an instrument I was to use.
+Mine eyes are made the fools o' the other senses,
+Or else worth all the rest; I see thee still,
+And on thy blade and dudgeon gouts of blood,
+Which was not so before.
+There's no such thing:
+It is the bloody business which informs Thus to mine eyes. 
+Now o'er the one halfworld Nature seems dead,
+and wicked dreams abuse The curtain'd sleep; witchcraft celebrates
+Pale Hecate's offerings, and wither'd murder,
+Alarum'd by his sentinel, the wolf,
+Whose howl's his watch, thus with his stealthy pace.
+With Tarquin's ravishing strides, towards his design
+Moves like a ghost. Thou sure and firm-set earth,
+Hear not my steps, which way they walk, 
+for fear Thy very stones prate of my whereabout,
+And take the present horror from the time,
+Which now suits with it.
+Whiles I threat, he lives:
+Words to the heat of deeds too cold breath gives.
+I go, and it is done; the bell invites me.
+Hear it not, Duncan; for it is a knell
+That summons thee to heaven or to hell.
