Writer and cartoonist Anthony Rubino, Jr. hilariously shares 101 inventions that bizarrely changed the world. Why Didn't I Think of That? proves not all successful inventions are the greatest thing since sliced bread (not even sliced bread, which is literally just a precut 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.
