There was an old professor who started every class with a vulgar joke. After one particularly nasty example, the women
in the class decided to walk out the next time he started. The professor got wind of this plot, so the next morning he walked
in and said: "Good morning, class. Did you hear the one about the shortage of whores in India?" With that, all the women stood
up and headed for the door. "Wait, ladies," cried the professor. "The boat doesn't leave until tomorrow!"
A new teacher was trying to make use of her psychology courses. She started her class by saying, "Everyone who thinks they
are stupid, stand up!" After a few seconds, Little Johnny stood up. The teacher said, "Do you think you're stupid, Little
Johnny?" "No, ma'am, but I hate to see you standing there all by yourself!"
