At least your impalement was not self-inflicted. I did something really clever when I was 14, which resulted in a welding rod being shot lengthways through my thumb. It entered at the base of the thumb and the tip of the rod came out at the tip of the thumb. It was right next to the bone, and stuck fast.
I won't say how it happened, but I will say that the particular 'research' I was doing (welding rods as projectiles) was ended the same day...permanently.
The doctor was a real {bleep}. He made me lie down and then jumped on my chest, pinned my hand and just ripped the welding rod out. I could feel the rough texture of it grinding against the bone. And he did it without sending me for X-rays first.
