Oh Man, this reminds me of something that happened when I was a kid. I took a old pitch fork handle and drilled a hole in the end. I tapped a big spike into the hole then sawed the head off and sharpened it up on the old peddle grinder. I was throwing it at the wind break by the barn and one of my throws went over the windbreak. I went around to pick it up and was horrified to see the home made spear sticking in the head of one of the milk cows. My dad had recently sawed her horns off and the spear stuck right into the flat spot left where the horn was. The blood was spraying three feet out of her head. She shook her head several times and finally whiped it loose. When my dad came home and saw the blood all over the cows head and neck, he warmed up my rear end pretty good. The old cow came out of it better than I did.
