By the pricking of my thumbs,
Something wicked this way comes.
By my warty nose’s twitch
Something dismal leaves the ditch. 
By the ticking of my brain
Something poxy writhes in pain.  
By the clicking of my jaw
Evil sharpens tooth and claw.  
By the tail of newt and shrew
Double trouble’s gonna brew. 
By the bubbling of my pot
I foresee a gory plot.
