Battery

Once when I was a small kid many years ago, my brother was sitting in the other end of the house and I was sitting on a couch in the other end of the house. So from that end he was trying to scare me by attempting to throw a battery at me. So he was like trying to scare me and I was like ducking here and there and trying to avoid being hit by the battery (even though he was not throwing it and in fact didnt want to). After a few times I stopped ducking and moving because I knew that he was just trying to scare me. But unfortunately for me while doing this a few times, suddenly the battery slipped out of his hand accidently and BANG it came and directly hit my head and after a few seconds there was a huge bump on my head. Some accidents just start off as fun but end in diaster and this was one of them...
