Amazing Elevator

A man from the country was visiting a big city for the first time. While walking through a large office building lobby, he noticed an old woman standing in front of two shiny metal doors.

The doors opened, the woman stepped inside, and the doors closed again. A few seconds later the doors opened and a beautiful young woman stepped out.

The country man stared in amazement, scratched his head, and then quickly turned to his son and said, "Go get your mother!"
