Oh man that looks pretty bad. When I was a teenager, my best friend and I were drinking beer in the woods behind his house. We were walking and he stepped on a board with a nail about 3 inches long sticking straight up. When he felt it go into his foot, he jumped up in the air and grabbed his injured foot. He came down full weight on his other foot on the nail and drove it all the way through his foot. That was a nice trip to the hospital for a tetnus shot.
