Quote of the Week: Fire Burn, and Cauldron Bubble

"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 owlet's wing,—
For a charm of powerful trouble,
Like a hell-broth boil and bubble.
Double, double toil and trouble;
Fire burn, and cauldron bubble."

—William Shakespeare, Macbeth
