Happy Halloween!

Round about the caldron go;
In the poison'd entrails throw.
Toad, that under cold stone,
Days and nights has thirty-one
Swelter'd venom sleeping got,
Boil thou first i' the charmed pot!

Double, double, toil and trouble;
Fire, burn; and caldron, bubble.

Fillet of a fenny snake,
In the caldron 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.

Double, double, toil and trouble;
Fire, burn; and caldron, bubble.

Scale of dragon, tooth of wolf,
Witch's mummy, maw and gulf
Of the ravin'd salt-sea shark,
Root of hemlock digg'd i' the dark,
Liver of blaspheming Jew,
Gall of goat, and slips of yew
Sliver'd in the moon's eclipse,
Nose of Turk, and Tartar's lips,
Finger of birth-strangl'd babe
Ditch-deliver'd by a drab,—
Make the gruel thick and slab:
Add thereto a tiger's chaudron,
For the ingredients of our caldron.

Double, double, toil and trouble;
Fire, burn; and caldron, bubble.

Cool it with a baboon's blood,
Then the charm is firm and good.
