Once there was a professor who always told dirty jokes in the class. One of the woman in his class wanted to protest against him. So to accomplish it she with other fellow women made a plan that when the professor will start a joke they will protest and leave the class. Fortunately or unfortunately somehow the professor came to know about the plan. So the next day when he entered the class he told his students that “Do you know in Sweden prostitutes earn $1000 per night.” The women as planned started protesting by leaving the class. Professor standing back hurriedly tried to stop them saying “The flight to Sweden won’t take off until tomorrow morning.” LOl!!
