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. In the cauldron boil and bake fillet of a fenny snake, scale of dragon, tooth of wolf, witch's mummy, maw and gulf. Double, double, toil and trouble, fire burn and cauldron bubble. Something wicked this way comes!
