Boggles, bugbears, and buggy-bones!

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