This above all: to thine own self be true

Polonius to Laertes

Something is rotten in the state of Denmark

Marcellus to Horatio

The serpent that did sting thy father's life
Now wears his crown.

Ghost to Hamlet

The time is out of joint. O cursed spite, that I was ever born to set right

Hamlet to self

Though this be madness, yet there is method in't.

Polonius to Hamlet

To be or not to be; that is the question...

Hamlet during his third soliloquy.

My words fly up, my thoughts remain below

Claudius to himself

O Hamlet, speak no more!

Gertrude to Hamlet

Good night, sweet Prince, and flights of angels sing thee to thy rest.

Horatio to Hamlet
