"Tomorrow, and tomorrow, and tomorrow, Creeps in this petty pace from day to day, To the last syllable of recorded time. And all our yesterdays have lighted fools The way to dusty death. Out, out!

Tis a tale told by an idiot Full of sound and fury, signifying nothing. The words which make the metaphors are "pace", "syllable", "candle", "shadow", "player", "tale".
