This happened in a Christmas Tournament game this year (well last year, but this basketball season
). It was the game after mine, and we stayed around for a little while and took advantage of the food!
Coach threw down his clip board on a call he didn't get, the officials were down on the other end of the floor and didn't see it. Then, there was a call that went against him... so he took a coin out of his pocket, threw it up, looked at the result, and shrugged his shoulders. Just when he thought he got away with it... the C (who was opposite table) came in with the call -- whack.
