An Amish boy and his father were in a mall.  
They were amazed by  almost everything they saw,  but especially by  two shiny silver walls that could move apart and then  slide back together again.
 
The boy asked, '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 with amazement, a  fat old lady in a wheelchair moved 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 the small numbers above the  walls light up sequentially. 
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 blond stepped out.
 
 
The father, not  taking his eyes off the young woman, said quietly to his  son..... 
'Go get your  Mother'
