Three idiots decide to go hunting. The first one says he’s going to get a buck. He goes out, and indeed comes back with a buck. The other two hunters ask how he did it. He says, “I see tracks. I follow tracks. I get buck.”
So the second hunter says that he’s going to get a doe. And he does. They ask him how he did it, and he says, “I see tracks. I follow tracks. I get doe.”
So the third hunter says, “I’m just gonna shoot at anything I see.”
So he goes out and comes back half a day later all beaten, bruised, bloody, and totally trashed. The other two hunters ask him what happened and he says, “I see tracks. I follow tracks. I get hit by train!”
