Jokes that arise when helping others

Three mental patients are sleeping on their stomachs.

Then the psychiatric director brought in a robot.

The first mental patient jumped up and shouted that aliens have invaded the earth.

The second mental patient stood there with a frightened expression and said don't kill me.

The third mental patient was very calm. The dean was very happy and asked, why are you not afraid?

The third mental patient grinned and said: "I'm so scared, I am an alien, and they are here to rescue me." ”
