A pair of star-crossed lovers take their life.
(Chorus, Prologue)

Abraham: Do you bite your thumb at us, sir?
Sampson: I do bite my thumb, sir.
(Act 1 Scene 1)

But, soft, what light through yonder window breaks?
It is the east, and Juliet is the sun.
(Romeo, Act 2 Scene 1)

O Romeo, Romeo, wherefore art thou Romeo?
(Juliet, Act 2 Scene 1)

That which we call a rose 
By any other word would smell as sweet.
(Juliet, Act 2 Scene 1)

Parting is such sweet sorrow.
(Juliet, Act 2 Scene 1)

For this alliance may so happy prove, 
To turn your households' rancour to pure love.
(Friar Laurence, Act 2 Scene 2)

These violent delights have violent ends.
(Friar Laurence, Act 2 Scene 5)

A plague o' both your houses!
(Mercutio, Act 3 Scene 1)

Mercy but murders, pardoning those that kill.
(Prince, Act 3 Scene 1)

O deadly sin! O rude unthankfulness!
(Friar Laurence, Act 3 Scene 3)

Hang thee, young baggage, disobedient wretch!
I tell thee what: get thee to church o'Thursday, 
Or never after look me in the face. 
(Capulet, Act 3 Scene 5)

Romeo, Romeo, Romeo! Here's drink: I drink to thee.
(Juliet, Act 4 Scene 3)

O true apothecary, 
Thy drugs are quick. Thus with a kiss I die. 
(Romeo, Act 5 Scene 3)

O happy dagger, 
This is thy sheath: there rust, and let me die.
(Juliet, Act 5 Scene 3)

All are punished.
(Prince, Act 5 Scene 3)

For never was a story of more woe 
Than this of Juliet and her Romeo.
(Prince, Act 5 Scene 3)
