Mine just happened recently. Had a really bad day at work, and took my anger out on a solid wood door. Not very bright. Broke the bone in my hand that connects to my pinky. I knew something bad happened because the back of my hand had a nice hump in it, so I went to the hospital. It didn't hurt too bad, until I went to turn the ignition key to start my car. YEEEOWWWWW!!
The nurse was cool though. I told her what happened and said "I just had a really, really bad day." She said "Awwwwwww.. Well we'll get you all bandaged up. And get you some Vicodin, too."
