The university professor told a joke in English.

This version is about a doctor, a lawyer, a boy and a priest.

The character is not good, but that's probably what it means.

A doctor, a lawyer, a little boy and a priest travel in a small private jet. Suddenly, the plane had engine trouble. Despite the pilot's best efforts, the plane began to descend. Finally, the pilot grabbed a parachute and shouted to the passengers that they had better jump. Then he parachuted.

Unfortunately, there are only three parachutes left. The doctor grabbed one and said, "I am a doctor, I save people, so I have to live" and jumped out.

The lawyer went on to say, "I am a lawyer, and lawyers are the smartest people in the world." I deserve to live. " He also grabbed the parachute and jumped.

The priest looked at the little boy and said, "My child, I have lived for a long time.". You are still young, and your life is still very long. Take the last parachute and live in peace. "

The little boy returned the parachute to the priest and said, "Don't worry, Dad. The smartest person in the world has just left with my backpack. "
