The first man was an engineer, the second an accountant, the third a chemist and the fourth was a public servant.

To show off, the engineer called to his cat, "T-Square, do your stuff."
T-square pranced over to the desk, took out some paper and a pen promptly drew a circle, a square and a triangle. Everyone agreed that was pretty smart.

The accountant said his cat could do better. He called his cat and said, Spreadsheet, do your stuff." Spreadsheet went into the kitchen with and returned with a dozen Tim Tams, he divided them into four equal piles of three each. Everybody agreed that was good.

The Chemist said his cat could do better. He called his cat and said, "Measure, do your stuff." Measure got up, walked over to the fridge, took out a litre of milk, got a 250ml glass from the cupboard and measured out 200mls without spilling a drop. Everyone agreed that was good.

Then the three men turned to the public servant and said, "What can your cat do?" The public servant called to his cat and said, "Coffee Break, do your stuff." Coffee Break jumped to his feet, ate the Tim Tams, drank the milk, on the paper, sexually assaulted the other three cats claimed he injured his back while doing so, filed a provisional improvement notice for unsafe working conditions, put in a claim for workers compensation and went home for the rest of the day on sick leave.
