Skinning a deer with a golf ball

I had always heard about this and never seen it actually done. A couple of our new hunt club members have been doing it for years and let me tell you it is pretty slick. If you don't know, you partially skin the deer. Split the skin down the legs and down the belly. Ring the skin around the legs and neck. Put a golf ball under the skin and a slip knot around it. Hook the other end to a ATV and drive off. The skin comes off the deer like a banana peel. It keeps the meat clean and free of hair
Here is a video on how it is done
