There's a certain joy in kicking a ball-- it's a similar pleasure to throwing something and hitting the thing you wanted-- but there's the added satisfaction that you did it with your foot . . . and my five year old son Ian understands this: the other day he spent a great deal of time and concentration trying to punt a soccer ball over the tennis court fence, which is an impressive feat for a forty pound child, and then once he accomplished it, he tried to do it again and again . . . and this reminds me of one of my favorite kicks of all time; it took place in our fraternity "pit," a carpeted area with benches and a television-- I was putzing around with a soccer ball-- and Kenny Bloom borrowed Brian Fogg's motorcycle helmet, sat on the bench, put on the helmet, and said to me, "Kick it at my head!" and I complied and I hit it hard and clean and perfect and it hit the helmet and snapped Kenny's head back and knocked the helmet clean off his head, and he looked at me, stunned, and said, "Remind me never to do that again."
