A family member once had a bale of hay set up to target shoot his archery stuff.
One arrow flew over the bale and killed a chicken in the neighbors yard.
Pure accident.
It went clear to and into the bone.
At the moment, it didn't seem to hurt. In a reflex move, I reached down and pulled it out...and it didn't look bad - just a round hole.
Than,all of a sudden, blood started pumping out like a faucet.
That did it. I started howling. My step dad came and got me. Unfortunately, he was a Christian Scientist and didn't believe in doctors...so no stitches, no antibiotics.
Fortunately, it didn't get infected but he had to carry me everywhere for 2 weeks as I couldn't walk on it.
I still have the soft round impression in my leg.
