This just came up in my fortune on my Mac:
The Commandments of the EE:
(5) Take care that thou useth the proper method when thou takest the measures of high-voltage circuits too, that thou dost not incinerate both thee and thy test meter, for verily, though thou has no company property number and can be easily surveyed, the test meter has one and, as a consequence, bringeth much woe unto a purchasing agent.
(6) Take care that thou tamperest not with interlocks and safety devices, for this incurreth the wrath of the chief electrician and bring the fury of the engineers on his head.
(7) Work thou not on energized equipment for if thou doest so, thy friends will surely be buying beers for thy widow and consoling her in certain ways not generally acceptable to thee.
(8) Verily, verily I say unto thee, never service equipment alone, for electrical cooking is a slow process and thou might sizzle in thy own fat upon a hot circuit for hours on end before thy maker sees fit to end thy misery and drag thee into his fold.
