You spotted snakes with double tongue,
Thorny hedgehogs, be not seen;
Newts and blind-worms, do no wrong,
Come not near our fairy Queen.
I have had a most rare vision. I have had a dream, past the wit of man to say what dream it was. Man is but an ass if he go about to expound this dream. Methought I wasthere is no man can tell what. Methought I was, and methought I had, but man is but a patchd fool, if he will offer to say what methought I had. The eye of man hath not heard, the ear of man hath not seen, mans hand is not able to taste, his tongue to conceive, nor his heart to report, what my dream was.
This is the silliest stuff that ever I heard.
WILLIAM SHAKESPEARE
A MIDSUMMER NIGHT S DREAM
Im nae listenin to them! Theyve got warts!
