 Good story.  Reminds me of my purchase of a TI scientific calculator back in 
the 1970's.  It had a factorial key (!).  You could enter 69! and the display 
would go blank for about 20 seconds while the calculation was being performed.  
I just ran the same calculation on this PC and the 
result:1.7112245242814131137246833888127e+98
came back in the blink of an eye. <grin>
