"Imagine someone who hates you with the utmost intensity grabbing a handful of your hair while you're lying prostrate and helpless. Then scraping the dull blade of a rusty knife across you scalp. And let your imagination grasp if you can, Mr. Graham, the effect that a strong, quick jerk on the turf of your hair to release any clinging particles would have on your nervous system."
