An engineer, an accountant, a chemistry expert and a state employee

An engineer, an accountant, a chemistry expert and a state employee began arguing whose cat is the smartest. The engineer called his cat:
- X2, Demonstrate!
The cat called X2 climbed on the table, took paper and pencil and drew a circle, a square and a triangle. Everyone agreed that this is an intelligent cat.
The accountant told his cat:
- Interest, demonstrate!
The cat Interest went to the kitchen and came back with 12 meat balls. He put them In 4 separate plates, 3 meat balls per plate and everybody agreed that this is an intelligent cat as well.
The chemistry expert called his cat:
- Test-tube, demonstrate!
The cat Test-tube went to the kitchen, brought milk and pored precisely 150 grams in a glass. They all agreed this is one intelligent cat as well.
At the end it was time for the cat of the state employee and he called it:
- Pamper, demonstrate!
The cat pamper ate the meatballs, drunk the milk, pissed on the drawings, raped the other tree cats, lamented his back hearts, wrote a complaint for the awful conditions of work, sent it to the municipality and took one month vacation because of health issues.
