Once there was a girl who lived with her father and they were very happy together. One day, her father had to leave on a business trip. He'd be gone a few days and he warned her not to answer the door while he was gone.
     That night, she had a weird dream and her father again warned her not to open the door.
     She was awoken by the sound of someone knocking on the door. She walked over to the door, calling, "Dad is that you?" No answer. She took a look through the peephole and saw her father at the door but something wasn't right. He had a look of fear on his face.
     Again she called, "Dad, is that you?" Still no answer.
    After asking a third time, the girl sat down in the hallway and opted to stay there until the knocking ceased. It continued all through the night....
     In the morning, the girl woke up to find the knocking had ceased. She walked to the door and opened it to find that her father's head had been nailed to the door with a message hung from his neck that said, "Clever girl."
