Lady Macbeth: Look like the innocent flower, but be the serpent under it.
Macbeth: Life's but a walking shadow, a poor player that struts and frets his hour upon the stage and then is heard no more. It is a tale told by an idiot, full of sound and fury, signifying nothing.
Macbeth [Aside]: If chance will have me king, why, chance may crown me without my stir.
Macbeth: So foul and fair a day I have not seen.
Macbeth: False face must hide what the false heart doth know.
Duncan: There's no art to find the mind's construction in the face.
Lady Macbeth: Out, damned spot! Out, I say!
Lady Macbeth: What's done cannot be undone.
Double, double toil and trouble; fire burn, and cauldron bubble.
Macbeth: I bear a charmed life, which must not yield,
To one of woman born.
