Not quit roping, but when I was a kid, my "crazy uncle Dick" took me out deer hunting. After walking for several hours, we spotted a little 4 point whitetail buck. Uncle Dick shot it and it went down like a sack of bricks.
We took off our packs, leaned the rifles against a tree, Uncle Dick took out his knife and we walked over to it. Just as my uncle bent down to grab the deer, it jumped up to all fours, Uncle Dick laying across its back holding onto an antler with one hand and stabbing wildly at its neck with the knife with the other hand. That deer shook him off but he wouldn't let go of its antler and kept stabbing it in the neck with a 3 1/2 buck knife. That deer was shaking its head so violently, his whole body was jerking around like a rag doll.
The deer finally dropped on its front legs and Dick kept stabbing like a wild man. Me, being about 12 or 13 at the time just stood there in amazement that the deer had gotten back up.
When the deer finally fell over, I can still picture him sitting on his knees, stabbing it 4 or 5 times on the ground, then sat there looking at me panting with blood all over his face and chest. I think about half of it was his own.
After we gutted it and took it home, the first thing my Aunt said to him when he walked in the door was "You got into another fight at the bar again, didn't you!?!"
