The boy asked, "What is this, Mother?"
The mother (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 mother were watching with amazement, an overweight old man in a wheelchair rolled up to the moving walls and pressed a button.
They continued to watch until it reached the last number and then the numbers began to light in the reverse order.
Finally, the walls opened up again and a gorgeous 24-year-old man stepped out.
The mother, not taking his eyes off the young man, said quietly to her son, "Go get your father."
