A boy and his Father went to a shopping mall. They were amazed by two shiny, silver walls that could move apart and back together again.

The boy asked his Father, "What is that Father?"

The Father responded, "Son, I have never seen anything like that in my life, I don't know what it is."

While the boy and his Father were watching, an elderly woman slowly walked up to the moving walls and pressed a button. The walls opened and the lady walked between them into a small room. The walls closed and the boy and his father watched small circles of lights with numbers above the walls light up.

They continued to watch the circles light up in the reverse direction. The walls opened up again and a gorgeous woman stepped out.

The Father said to his son, "Go get your Mother".
