As a child, I had naturally wavy hair, and my sisters hair was stick straight. My mom used to tell her, "If you eat your crusts, it'll make your hair curly." But she was no fool. She ate and ate them until she finally picked up on the fact that I was throwing my crusts to our dog, and yet my hair was curly. She was pretty mad. She still brings it up even to this day.
