Accidentally dropped my new Japanese kitchen knife but managed to catch it before it hit the ground.... Carefully removed new Japanese kitchen knife from the deep cut in my thumb where I'd caught the corner of the blade near the handle. Said many bad words. Had been soldering bits of brass together for a project and added some copper bits. Forgetting just how conductive copper is I was holding the piece of copper about 50-60mm from where I was soldering and promptly burnt my finger tips. Later on in a different project, for the same reason, found when doing one last solder joint that took a bit longer than usual, all the nearby joints suddenly fell apart. More bad words ensued. MANY years ago, I was setting up lights for a school function and was perched on the frame of a basketball backboard attaching a light to the board when I managed to put my finger in the socket and the obvious occurred. I managed not to fall of the frame, but got a good whack in the arm. I learned that lights aren't usually switched on both poles and that the panel was on! Also said bad word, loudly, which given it was at school caused much amusement. As the class nerd, it was the last thing anyone expected of me. I've had a few more "encounters" with mains AC so I'm probably lucky to still be around. Also a few more when I've tried to catch things I shouldn't have tried to catch. It's a bad habit!
