One Friday evening a man with three daughters answered a knock on the door.
A young man stood there, saying, "Hi, I'm Freddy. I'm here to get Betty. We're going to get spaghetti." The father told Betty that Freddy was there.
A few minutes later there was another knock on the door. The young man there said, 'I'm Louie. I'm here to get Susie. We're going to a movie." The father went and told Susie her movie date was there.
Ten minutes later there was a knock on the door. A young man there said, "Hi, my name is Chuck..."
The father shot him.
