I was shooting a Little League game where I had to do some serious smooching to get the umpire to let me on the field. He told me about 30 times to be careful to not get hurt. Probably the third or fourth pitch of the game got fouled off really hard right at me. I was against the fence, about two-thirds of the way down the first base line, and I stepped back but my back hit the fence, and the ball rocketed off my stomach. The first base coach (who'd witnessed all my pregame negotiating with the ump) exclaimed, "Wow, just missed ya!" Not wanting to get tossed, I made an exaggerated "whew" gesture with my hand across my forehead. The ump--who later proved in other ways that his eyesight wasn't so great--fell for our act, and I spent the next 45 minutes resisting the urge to rub my sore abs.
Last week, I caught a knee in the head during a swim meet (my fault...I was trying to get down low and failed to get the knee-wielder's attention beforehand) and learned why Canon puts padded eyecups on its cameras. (Thanks, Canon!)
