A guy I worked with once has a half of an arm because of a birth defect (other arm is a normal one). Great ref, worked many years. One day, we were working a very tight game, and he was approaching the table to report a foul, and out of the stands comes: "hey ref, do you got one eye too?" He had to chuckle, and said, no, but my partner only has one ear! It got really quiet in the gym, and I chuckled and told the players, this may be the only time you'll have two "disabled" guys on the floor with you. Never saw so many deer in the headlights looks. LOL
