"They were, after all, wizards.ย That meant that if they saw something, they prodded it.ย If it wobbled they prodded it some more.ย If you built a guillotine, and then put a sign on it saying โDo Not Put Your Neck On This Blockโ, many wizards would never have to buy a hat again."
- Terry Pratchett, with Ian Baxter and Jack Cohen - The Science Of Discworld #1
