One man was an engineer, the second man was an accountant, the third man was a lawyer, and the fourth was a CWA steward.
To show off, the engineer called to his dog. "T-square, do your stuff." T-square trotted over to a desk, took out some paper and a pen, and promptly drew a circle, a square, and a triangle.
Everyone agreed that was pretty smart.
The accountant said his dog could do better. He called to his dog and said, "Spreadsheet, do your stuff." Spreadsheet went out into the kitchen and returned with a dozen cookies. He divided them into four equal piles of three cookies each.
Everyone agreed that was good.
The lawyer said his dog could do better still. he called to his dog and said, "Docket, do your stuff." Measure got up, walked over to the fridge, took out a quart of milk, got a ten-ounce glass from the cupboard, and poured exactly eight ounces without spilling a drop.
Everyone agreed that was pretty impressive.
Then the three men turned to the CWA telecom employee and said, "What can your dog do?"
The CWA union employee called to his dog and said, "Coffee Break, do your stuff." Coffee Break jumped to his feet, ate the cookies, drank the milk, claimed he had injured his back while doing so, filed a grievance report for unsafe working conditions, put in for worker' compensation, and went home for the rest of the day on sick leave.
