Schick is trying to sell a computerized crystal ball he's 
recently invented to a marketing executive, but the executive 
is very skeptical. Schick says, "Go ahead and type a question 
into the crystal ball." The executive types, "Where is my father?"
The crystal ball answers, "Your father is fishing in Michigan."
The executive says to Schick, "I knew this was bullshit. My father's
been dead for twenty years." The inventor says, "Ask the question 
in a different way." The executive types in, "Where is my mother's 
husband?" The computer answers, "Your mother's husband has been dead 
for twenty years. Your father just landed a three pound trout."
