I used to think that the guy who came up with the idea for Velcro (“velour crochet”) was a super-genius. I mean, it's simple yet simultaneously complex. It turns out that whoever that guy was, he cheated. He peeked at the answers that Mother Nature provided and copied them when the teacher wasn't looking. He saw how Burdoch burrs stuck to his tweed pants, took a closer look under the microscope, then patented the process. Cheater!
