An old professor’s class used to begin with a dirty joke.
Following one particularly vulgar joke, the girls in the class decided to walk out the next time he began.
When the professor learned of this planned protest, he came in the next morning and said, “Good morning, class. Did you hear about the scarcity of whores in Newfoundland?”
With that, all the women stood up and headed for the door.
“Wait, ladies,” called the professor, “The boat doesn’t leave until tomorrow!”
