You know, it's been 16 years since I performed it, and I still remember most of it. There are so many great lines in that play. The Tomorrow^3 bit stands out, and I probably use it the most. Still, there are many others:
Tomorrow^3 (just for completeness)
"She should have died hereafter;
There would have been a time for such a word.
To-morrow, and to-morrow, and to-morrow,
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, 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: it is a tale
Told by an idiot, full of sound and fury,
Signifying nothing."
"Yet I will try the last. Before my body
I throw my warlike shield. Lay on, Macduff,
And damn'd be him that first cries, 'Hold, enough!'"
"If thou speak'st false,
Upon the next tree shalt thou hang alive,
Till famine cling thee: if thy speech be sooth,
I care not if thou dost for me as much.
I pull in resolution, and begin
To doubt the equivocation of the fiend
That lies like truth: 'Fear not, till Birnam wood
Do come to Dunsinane:' and now a wood
Comes toward Dunsinane. Arm, arm, and out!
If this which he avouches does appear,
There is nor flying hence nor tarrying here.
I gin to be aweary of the sun,
And wish the estate o' the world were now undone.
Ring the alarum-bell! Blow, wind! come, wrack!
At least we'll die with harness on our back."
I could go on, but really most of the play is awesome. It's probably my favorite Shakespeare.
