Funny, Welpe.
But you neglected to include the light bulb.
Everyone else in the gym knew that 21 fouled. The crowd (well, half perhaps) voiced their opinion when 23 was reported. The Team A coaching staff knew - and let me know. B#23 looked puzzled. The other players didn't say anything. I didn't know that the L reported 23. But when the coach asked me, I put 2 and 2 together and realized that the booing was from the wrong number, not the clear and obvious foul.
So I approached the calling official. We had a discussion, and he stayed "happy" with his call, despite the multiple points that I brought to him. In fact, during our conference, one fan even said "it was 21"; but that could have easily been missed amongst the plethora of crowd noise.
I don't have my book with me at present, nor PDFs, so I can't look up the exact language. There is a statement that if the two officials disagree, then the Referee shall make the final decision. I was the Umpire in the game, but if I was the Referee, using that privilege ensures that the call is correct.
