The teacher was deeply engaged in discussing advanced technologies when he suddenly said:
“Nowadays, advanced technology allows people to create fully automated production lines; on one end, you put in a cow, and on the other end, the machine produces a perfect sausage!”
Suddenly, a student spoke up:
– “Excuse me, teacher, is it possible to create a machine that does the opposite?”
The teacher, quite irritated, replied:
– “Yes, about ten years ago, your father put a sausage into a machine, and it spat out a cow; that’s you!”
