A Kentucky family took a vacation to New York City. One day, the father

took his son into a rather 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 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 above the walls light up. They continued to watch the circles light

up in the reverse direction. The walls opened again, and a voluptuous

24-year-old woman stepped out.
