Double, double toil and trouble

An excerpt:

Double, double toil and trouble;
Fire burn and cauldron bubble.
Fillet of a fenny snake,
In the cauldron boil and bake:
Eye of newt and toe of frog,
Wool of bat and tongue of dog,
Adder's fork and blind-worm's sting,
Lizard's leg and howlet's wing,
For a charm of powerful trouble,
Like a hell-broth boil and bubble.

~ from Macbeth, Act IV, Scene 1,

written by William Shakespeare

I've never actually seen a performance of Macbeth, and I'm not sure that I've ever read the entire play, but I have read through parts of it before, including this scene.  I love Shakespeare's eerie chant-like rhymes....
