Fire Burn and Cauldron Bubble

I always liked the witches in Macbeth and Lady Macbeth.

'Out damned spot! Out I say!'

'Naught's had, all's spent
Where our desire is got without content.
'Tis safer to be that which we destroy
Than, by destruction, dwell in doubtful joy.'

'When shall we three meet again
In thunder, lightning, or in rain?'
'When the hurly-burly's done,
When the battle's lost and won.'

Definitely my favourite Shakespeare play.
