This book proves not all successful inventions are the greatest thing since sliced bread (not even sliced bread, which is literally just a pre-cut loaf for lazy loafs). This humorous guide to mind-blowing inventions deconstructs just how complex these can't-live-without necessities really are, while providing some insightful(ly funny) lessons to future inventors, such as: Yo-yos—deadly weapons do make great kids' toys; Soccer—boredom is the stepmother of invention; Bottled water—there is no such thing as a stupid idea. Complete with useful trivia—like the fact that 100 trillion paperclips have been sold—readers will be able to impress their friends by hardly trying.
