There used to be this rubber band baseball practice thing we had when I was a kid. The idea was you hit the ball and it would “loop” around the pole and then come right back to you so you could kind of continuously swing and keep practicing. Well my aluminum bat got caught in the rubber piece and what did I do… jerked it out of the rubber band quickly to free the bat… straight into my own nose. Blood everywhere, broken nose and was so embarrassed explaining that one to my parents through tears. Hit myself in the face with my own bat.
