There was that day in my living room, when I was clipping my toenails, and one of them catapulted into the air and hit me right dead center of the bald spot on top of my head. Prior to that, I had had no idea that the curvature of a toenail (my big toe toenail does resemble the aerodynamics of  a boomerang) could produce such a perfect bend-it-like Beckham trajectory when clipped. (Okay, too much exposition?)
