I am stealing the "shame stick" idea. We had a guy who shot a poor spike 4 times on the land next to us. The deer ran off, then one of my buddies-relatives had to finish it off with a fifth shot after it ran right up to his stand and stood there with, as he put it, a "just shoot me, and do it right this time" look.

The joke that night was "you missed one of the legs Joe....."
