And thou shalt eat it as barley cakes, and thou shalt bake it with dung that
cometh out of man, in their sight...Then he [the Lord!] said unto me, Lo, I
have given thee cow's dung for man's dung, and thou shalt prepare thy bread
therewith.
[Ezek. 4:12-15 (KJV)]
A novice was trying to fix a broken lisp machine by turning the
power off and on. Knight, seeing what the student was doing spoke sternly,
"You cannot fix a machine by just power-cycling it with no understanding
of what is going wrong." Knight turned the machine off and on. The
machine worked.
"I'd love to go out with you, but I'm doing door-to-door collecting for static
cling."
