I would pick those ones:
Two households, both alike in dignity,
In fair Verona, where we lay our scene,
From ancient grudge break to new mutiny,
Where civil blood makes civil hands unclean.
From forth the fatal loins of these two foes,
A pair of star-cross'd lovers take their life;
Whose misadventured piteous overthrows,
Doth with their death bury their parents' strife.
But, soft! what light through yonder window breaks? It is the east, and Juliet is the sun! Romeo, Act II scene II
O woe! O woeful, woeful, woeful day!
Most lamentable day! Most woeful day
That ever, ever I did yet behold!
O day, O day, O day! O hateful day!
Never was seen so black a day as this.
O woeful day! O woeful day!
Nurse, Act IV scene v O true apothecary! Thy drugs are quick. — Thus with a kiss I die. Romeo, Act V scene iii Yea, noise? then I'll be brief. O, happy dagger! This is thy sheath; there rest, and let me die. Juliet,Act V scene III
