Three engineers were in the bathroom standing at the urinals. The
first engineer finished and walked over to the sink to wash his hands.
He then proceeded to dry his hands very carefully. He used paper towel
after paper towel and ensured that every single spot of water on his
hands was dried. Turning to the other two engineers, he said, "At
Hewlett Packard, we are trained to be extremely thorough."

The second engineer finished his task at the urinal and he proceeded
to wash his hands. He used a single paper towel and made sure that he
dried his hands using every available portion of the paper towel. He
turned and said, "At Lockheed-Martin, not only are we trained to be
extremely thorough, but we are also trained to be extremely
efficient."

The third engineer finished and walked straight for the door, shouting
over his shoulder, "At Apple Computer, Inc. we don't pee on our
hands."
