Url,
Along the same vein...General Freiherr Von Hammerstein-Equord, German Army first.

"I divide my officers into four classes as follows: the clever, the industrious, the lazy, and the stupid. Each officer always possesses two of these qualities.
Those who are clever and industrious I appoint to the General Staff.
Use can, under certain circumstances, be made of those who are stupid and lazy.
The man who is clever and lazy qualifies for the highest leadership posts. He has the requisite nerves and the mental clarity for difficult decisions.
But whoever is stupid and industrious must be got rid of, for he is too dangerous."

-- General Freiherr Von Hammerstein-Equord, German Army (1933)

Its an old cartoon, but still a good one :)

Reminds me somewhat of Myrtle the Turtle. If you don't know the story, look it up. There is a certain poignancy to these cartoons that they lacked in yesteryear. They would go well as illus in the book "Who Moved My Cheese."
