What was the name of this hillarious hunting game?

I've been looking for a download of this old hunting game that I came accross online, about 10 years ago. All that I remember, is that it is a cartoony looking 3d, first person deer hunting game. Theyre are other small animals as well. When you shoot them funny things happen, like heads explode, your character says smart *** things. I also remember there is a multi level Christmas addition, where you can hunt santa's elves. Anyone know what Im talking about?
