Amish and an Elevator

An Amish boy and his father were visiting a mall. 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 (never having seen an elevator) 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 and into a small room. The walls closed and the boy and his father watched
small circles of light with numbers above the wall light up. They continued to
watch the circles light up in the reverse direction. The walls opened up again
and a beautiful 24 year old woman stepped out. The father said to his son, "Go
get your Mother."
