... at a Silicon Valley bar, and one of them says to the other,
``What's your IQ?''
``250.  What about you?''
``240.''
They begin a heated debate about grand unified theories, wormholes, NetBSD
;-),
quantum physics, and such things.

A little further down the bar are two other guys, sipping their drinks.
``What's your IQ?''
``200.  You?''
``180.''
They turn their conversation to interpreting Kant, Monet, Shakespeare,
and other masters of philosophy, art, and literature.

Still further down the bar are two more guys.
``What's your IQ?''
``115.''
``Mine's 120.''
They begin arguing about chess strategies and the merits of this
opening versus that one.

At the end of the bar are two more guys.
``Well ... what's your IQ?''
``60.  Yours?''
``45.  So, do you use click-to-focus or sloppy focus?''
