At one point during a game, the coach called one of his 10-year-old basketball players aside and I asked, "Do you understand what cooperation is? What a team is?" The little boys nodded in the affirmative.

"Do you understand that what matters is not whether we win or lose, but how we play together as a team?" The little boys nodded yes.

"So," the coach continued, "I'm sure you know, when a penalty is called you shouldn't argue, curse, attack the referee, or call him a pecker-head. Do you understand all that?" Again the little boys nodded.

The coach continued, "And when I call you off the field so that another boy gets a chance to play, it's not good sportsmanship to call your coach "a dumb a-hole," is it?''
Again the little boys nodded.

"Good," said the coach. "Now go over there and explain all that to your mothers!"
