In third grade, I opened my piano bench in search of my piano books, but I tipped it too far and it flipped over onto my foot. I immediately began screaming, and my dad ran into the room and ripped my sock off. My big toe was bleeding from under the toenail.

When we got to the ER, I got a very arrogant young doctor who got really mad at me for "overreacting" and crying so much. He made me wait forever, and then he finally explained that kids stub their toes hard enough for their toenails to fall off all the time, but it was a superficial wound and he was going to just rip mine the rest of the way off before sending me home. As soon as he did so, the expression on his face went from smug to "oh shit" immediately. In ripping my toenail off, he had degloved part of my toe, and revealed that the piano bench had cut so deeply that my bone was actually exposed.

I ended up getting 64 stitches, and I had to spend 2 weeks with my toe above my heart. Years later, my parents told me that the doctors had recommended amputating my toe due to the high infection rate on serious foot injuries and the fact that the doctor hadn't worn gloves when ripping off my toenail. Thank god my parents told them not to.

TL;DR--I opened a piano bench incorrectly and almost had my big toe amputated
