The Spinning Jenny

Hello I have made a new invention, it is called 'Spinning Jenny'
Excellent! What does it do?
Hello basically, it knacks and maims poor children. If it doesn't do that then it makes them develop a hunchback, slowly, over about 5 years. As a side-product it creates yarn
Excellent! I shall buy a dozen. I have some unused buildings in Clackmannshire. I shall install your machines and invite the local poor to send their children for a groat each. To dispose of the yarn, I shall burn it
