I once hit a squirrel in the side of the head with a wormburner tee shot. As we walked up to what we thought was a dead squirrel, it sat up, shook itself, and tried to run to the nearest tree. Every few feet, it toppled over and had to right itself to run a few more steps. It finally made it to the safety of the tree, but that did nothing to relieve the incredible amount of needling I got for the rest of that round.
