Many years ago, I was working a game with the immortal Dave. I was ref, he was umpire. I tossed. A1 tipped the ball, it hit B1 on the shoulder and then A1 grabbed it. Dave didn't blow his whistle and I wasn't really paying attention to that area so play continued. At the first break, coach B asked us why A1 was allowed to do that. Dave told him the ball had hit a "non-jumper" so it was legal. As we walked away, I asked Dave who the "non-junper" was. He said it was B1 - he had worked a number of his games and he hadn't seen him jump yet!
