A 12 year old boy and his father are new to the Western World and entered a mall for the first time.
The boy was amazed by everything he saw, but especially by 2 silver doors that move apart and then slide back together again.

The boy asked, “Dad. You’re an Engineer. What is this?”

The Engineer (never having seen an elevator before, but too proud to admit it) responded, “Son, this is an elevator. I’m very familiar with this because I’m an Engineer.”

While the boy watched with amazement, a fat brunette lady moved up to the moving walls and pressed a button.

The walls opened, and the fat lady walked between them into a small room.

The proud Father stated “See son, this will take her to the 2nd floor, then back down here to the 1st floor. I know this because I’m an Engineer”

The doors closed, and they watched as the numbers above the doors light up. From 1 to 2, then 2 to 1. 

Finally, the walls opened up again and a gorgeous brunette stepped out.

The Father, not taking his eyes off the young woman, said quietly to his son… 

“Wholly wow! Go get your Mother, now.”
