Elevator Magic

A hillbilly family took a vacation to New York City. One day, the father took his son into a large building. They were amazed by everything they saw, especially the elevator at one end of the lobby. The boy asked, "What's this, Paw?"
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 in wide-eyed astonishment, 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 above the walls light up. They continued to watch the circles light up in the reverse direction. The walls opened again, and a voluptuous twenty-four-year old woman stepped out.
The father turned to his son and said, "Go get your maw!"
