A mathematician, an accountant, a chemist, and a bureaucrat were bragging about their smart dogs.
The mathematician called to his dog: "T-Square, do your stuff." The dog took out paper and pen, and drew a circle, a square, and a triangle. Everyone agreed he was smart.
The accountant called to his dog: "Data, do your stuff." The dog went to the kitchen, got a dozen cookies and made four stacks of three. Everyone was impressed.
The chemist called to his dog: "Beaker, do your stuff." The dog went to the fridge for a quart of milk, got a ten-ounce glass and poured exactly eight ounces without spilling a drop. everyone agreed that was great.
The bureaucrat called to his dog: "Coffee Break, do your stuff!" The dog ate the cookies, drank the milk, chewed the paper, claimed he injured his mouth doing so, filed a grievance against the mathematician, put in for Workers' Compensation, and took an extended sick leave.
