Double Trouble - Harry Potter

Double double toil and trouble
Fire burn and couldren bubble
Double Double toil and trouble
Something wicked this way comes

Eye of newt and toe of frog
Wool of bat and tounge of dog
Adder's fork and blind worm's sting
Lizzard's leg and howlet's wing

In the cauldren boil and bake
Fillet of a fenny snake
Scale of dragon tooth of wolf
Witches mummy maw and gulf

Double Double toil and trouble
Fire burn and cauldren bubble

Double Double toil and trouble 
Fire burn and cauldren bubble 
Fire burn and cauldren bubble

Something wicked this way comes
