There was a cowboy riding in a desert when he saw a little girl up ahead. He heard her crying, so he went up to her and climbed down from his horse and asked her: "Hey, what's going on? Why do you cry? Where are your parents? What happened?"
The girl said in a crying, sad voice, "The Indians came, killed my father and my mother, and raped my sister."
The cowboy just laughed, unlocked his belt, and pulled his trousers down and said, "Guess it isn't your day, is it?"
