Hakeem 'The Dream' Olajuwan signed a basketball which was then thrown into the stands by the mascot. It was caught be a fan, who immediately gave the ball to a kid. That is how an adult should act at a professional sports game.
ALSO, the fan happened to be Tuffy Rhodes, a former Major League Baseball player who played for the Astros and the Cubs. I'm sure he knew the kid would get more joy from that ball than he would.
