The Shiny Round Rival

I scrambled across the floorboards on all fours until a glint caught my eye under the low coffee table. It was a real metal coin lying flat in the shadows! Naturally, I challenged it to a spin-off right then and there. I grabbed the edge of the bronze disk with both hands, gave a fierce twist, and sent it spinning across the smooth wood. Then I leaned back, dug my heels in, and tried to twirl myself on my rim! I wobbled, lost balance, and flopped straight onto my back with a soft thud. But that coin was still spinning like a champion. Next round is mine!
