A boy and his father visiting from a third world country were at
The Mall of America. They were amazed by almost everything they
saw, but especially by two shiny, silver walls that could move
apart and back together again.
The boy asked his father, "What is this father?" The father
responded, "Son I have never seen anything like this in my life.
I don't know what it is!"
While the boy and his father were watching wide-eyed an old lady
in a wheel chair rolled up to the moving walls and pressed a
button. The walls opened and the lady rolled between them into a
small room. The walls closed and the boy and his father watched
small circles of lights w/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 voluptuous 24 year
old woman stepped out.
The father said to his son, "Go get your mother."
