I don't remember specifics, but many many years ago, we had a Little League team playing an all-star game somewhere. The team was using the first base dugout. The third baseman was ahead of the pitcher walking out onto the field. He picked up the ball and proceeded to goof off and throw a pitch from the mound to the catcher. As a result, the umpire required him to throw the first pitch of the inning.
Needless to say, the coach told them to leave the game ball alone after that.
