A Rolled-Up Relay

I hopped down from the dining chair straight onto the soft woven living room rug! Right there in the open lay a freshly laundered pair of white sport socks rolled tightly into a ball. What an irresistible rolling target! I spread my wings wide, lined up my stance, and charged straight ahead with a burst of speed. Bonk! I slammed my round tummy square into the sock roll. It tumbled across the carpet fibers, bumped harmlessly into a chair leg, and wobbled to a halt right at my feet. First-place finish!
