An Amish boy and his father were in a shopping centre. They were amazed by almost everything they saw but especially by two shiny, silver walls that could move apart then slide back together again.
The boy asked, "What is this, Father?"
The Father (never having seen an Elevator before) responded, "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 with amazement, an obese older women in a wheel chair moved up to the moving walls and pressed a button.
The walls opened and the lady rolled between them into a small room. When the walls closed the pair watched the small circular numbers about the walls light up one after the other.
They continued to watch until it reached the last number and then the numbers began to light up in the reverse order.
Finally the walls opened up again and a gorgeous 24-year-old blonde stepped out. The Father, not taking his eyes off the young women, says quietly to his son, "Quick, go get your mother."
