"Fair is foul, and foul is fair." 

"Is this a dagger which I see before me, the handle toward my hand?"  

"Double, double, toil and trouble; fire burn and cauldron bubble."  

"Double, double, toil and trouble; fire burn and cauldron bubble."  

"By the pricking of my thumbs, something wicked this way comes." 

"Out, damned spot! Out, I say!"

"All the perfumes of Arabia will not sweeten this little hand."

"Fair is foul, and foul is fair: Hover through the fog and filthy air." 

"What's done cannot be undone." 

"By the grace of Grace, we will perform in measure, time, and place."  

"Out, out, brief candle! Life's but a walking shadow, a poor player that struts and frets his hour upon the stage and then is heard no more."
