Double Double Toil and Trouble

'Tis time! 'tis time! Round about the cauldron go In the poison'd entrails throw Swelter'd venom sleeping got, Boil thou first i' the charmed pot! 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, Double, double toil and trouble Fire burn and cauldron bubble. 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 cauldron bubble. Scale of dragon; tooth of wolf; Witches' mummy; maw and gulf Of the ravin'd salt-sea shark; Root of hemlock digged in the dark Double, double toil and trouble; Fire burn and cauldron bubble. Ditch-delivered by a drab, Make the gruel thick and slab Add thereto a tiger's chaudron, For the ingredients of our cauldron.        Double, double toil and trouble; Fire burn and caldron bubble. Cool it with a baboon's blood, Then the charm is firm and good. And now about the cauldron sing, Like elves and fairies in a ring, Enchanting all that you put in By the pricking of my thumbs, Something wicked this way comes Double, double toil and trouble; Fire burn and cauldron bubble. Double, double toil and trouble; Fire burn and cauldron bubble. Double, double toil and trouble; Fire burn and cauldron bubble. Open, locks Whoever knocks.
