Now I will believe that there are unicorns... - William Shakespeare

All causes shall give way: I am in blood
Stepp’d in so far that, should I wade no more,
Returning were as tedious as go o’er.

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, — For a charm of powerful trouble,
Like a hell-broth boil and bubble.
Double, double toil and trouble;
Fire burn, and caldron bubble.

Blow, winds, and crack your cheeks! Rage! Blow!
You cataracts and hurricanoes, spout
Till you have drenched our teeples, drowned the cocks!
You sulphurour and thought-executing fires,
Vaunt-couriers to oak-cleaving thunderbolts,
Singe my white head! And thou, all-shaking thunder,
Strike flat the thick rotundity o' the world!
Crack nature's molds, all germens spill at once
That make ingrateful man!
