During a school football match, the PE teacher called one of his 7-year-old players aside and asked, "Do you understand what cooperation is? What a team is?" The little boy 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 boy nodded "Yes".
"So," he continued, "I'm sure you know, when a penalty is called, you shouldn't argue, swear at/attack the referee, or call him rude names. Do you understand all that?" Again the little boy nodded.
He continued, "And when I call you off the pitch so that another child gets a chance to play, it's not good sportsmanship to call your PE teacher a stupid a*sehole', is it?" Again the little boy nodded.
"Good," said the PE teacher, now go over there and explain all that to your mother please."
