This is a new type of joke: the antartian joke. Antartian jokes are popular in the United States. The word "Antartian" cannot be found in any dictionary, but it means a stupid person.
An Antartian boy and his father were visiting a shopping 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 wheelchair rolled up to 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 light 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 beautiful 24-year-old woman stepped out. The father said to his son, "Go get your mother"
