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
