Thunder and lightning. Enter three Witches.
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.
That will be ere the set of sun. 
Where the place?
Upon the heath.
There to meet with Macbeth.
I come, Graymalkin.
Paddock calls. 
Fair is foul, and foul is fair,
Hover through the fog and filthy air.
