In the yard next to the Illbillys there was this kiddie pool, into which all kiddies leapt at one point or another. There were also plenty of water balloons & squirt guns, all of which are vaguely terrifying to musicians who are holding electrified things such as guitars, but no lives were lost. In the center of the picture we see JB's lovely wife Jill and manly son Jake, who is preparing to violently slap himself in the face with both hands. In the foreground we see evidence of Jack's masterful plan to include the kids who were up front by providing them with percussion instruments and inviting them to bash along, which they did with great gusto.
