A boy and his father, who were visiting from a third world country,
were at a mall. They were amazed by almost everything
they saw, but especially by two shiny, steel 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 wheelchair 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 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 voluptuous 24-year-old woman stepped out.
The father said to his son, "Quick, go get your mother!"
