Four men are bragging about how smart their cats are. The first man is an engineer, the second man is an accountant, the third a chemist and the fourth man is a mechanic.
To show off, the Engineer calls his cat, “T-square, do your stuff.” T-square prances over to the desk, takes out some paper and pen and promptly draws a circle, a square, and a triangle. Everyone agrees that hes pretty smart.
However, the accountant thinks his cat can do better. He calls his cat, “Spreadsheet, do your stuff.” Spreadsheet goes out to the kitchen and returns with a dozen biscuits. He divides them into four equal piles of three biscuits. Everyone agrees that hes good.
But the chemist says his cat can do better. He calls his cat, “Measure, do your stuff.” Measure gets up, walks to the fridge, takes out a pint of milk, gets a ten ounce glass from the cupboard and pours exactly eight ounces without spilling a drop into the glass. Everyone agrees that hes pretty good.
Then the three men turn to the mechanic and ask, “What can your cat do?” The mechanic calls his cat, “Coffee Break, do your stuff.” Coffee Break jumps to his feet, eats the biscuits, drinks the milk, craps on the paper, screws the other three cats, claims he injured his back while doing so, files a report for unsafe working conditions and goes home for the rest of the day on sick leave.
