Doubt thou the stars are fire, Doubt that the sun doth move.... - William Shakespeare

"If music be the food of love, play on."

"This life, which had been the tomb of his virtue and of his honour, is 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."

"We know what we are, but not what we may be."

"A lover goes toward his beloved as enthusiastically as a schoolboy leaving his books, but when he leaves his girlfriend, he feels as miserable as the schoolboy on his way to school. (Act 2, scene 2)"

"Come, gentlemen, I hope we shall drink down all unkindness."
