When the author was a kid, his brother Tom and him went through a series of replacement games until they settled on a winner called Knight Versus Peasant (KvP). KvP wasn't so much a game as it was an exercise in pain tolerance. Not surprisingly, KvP ended not long afterward, and they pioneered numerous other household combat sports. Eventually, their parents got hip to the fact that they were killing each other, and they tried to talk some sense into them. The truth is, they were the ones sustaining the injuries, so they knew better than anyone. To this day, they still talk fondly about those childhood battles, as if they really were worth the risk of getting a mess of stitches, or worse.
