I have heard of deer that,during fighting one dies and the has hoofed the head off the dead one and the deeer has another deers head on it.
But when I was looking at pictures on Dicks Sporting goods bragging board, there was two pictures of a kid that had shot a two headed buck on 11/25/06 in English IN. I done a Yahoo search and can't find anything at all about any two headed deer. This is a single body deer, which supposedly had two of it's own heads.
