I jumped to head the ball, but I missed it. On the way down something horrible happened. My left foot landed on an old yucky pencil. It pierced my foot. It dug in like a digger digging a hole. Blood poured out. I could not even stand on my foot. I had to hobble to the sick bay to get Dettol® and a plaster.
Nearly a week later I could walk on it like normal.
