Macbeth to His Lady.

Macbeth: There's comfort yet; they are assailable.
Then be thou jocund. Ere the bat hath flown
His cloistered flight, ere to black Hecate's summons
The shard-born beetle with his drowsy hums
Hath rung night's yawning peal, there shall be done
A deed of dreadful note.

Shakespeare, Macbeth, III, ii


Guess what he's planning? Talk about going to extreme lengths to impress a woman! I love the sound of this. If you say it out loud you can really hear how he's playing with sound (consonance, assonance, and alliteration), while actually talking about sound ("hums", "rung", "peal", "note")!

I was watching some show that heavily borrowed from Macbeth -- the very well-trodden depiction of him being unable to mentally wipe the blood and violence of murdering the King from his mind (or his hands). So, I pulled it out to read that section again and re-discovered this little passage, as well.
