Bad things happen to me frequently. Just this morning I half woke up. I had been lying on my arm and it had pins and needles. I somehow raised it up in the air while stretching and then instead of guiding it down to beside my hip the pins and needles stopped my muscle control and my arm fell straight down. As it happens, my fist fell square on my nose, fully awakening me in a thrash and yelling and much punching of thin air. I thought someone attacked in my sleep.
Anyway, worst situation was probably when I broke a kid's arm at school.
