Until a few years ago, only boys could become students at the University of Ruritania. Then the University decided to allow girls in. But one of the lecturers, Dr. Goller, was not at all pleased. He had not wanted to let girl students in.

Dr. Goller always used to begin his lectures with the word, “Gentlemen!” What would he do now? Well, when girl students came to his lectures for the first time, he continued to begin with the word, “gentlemen” For him, the girls were just not there.

Then one day there was only one boy in his class among a lot of girls. For a moment, Dr. Goller did not know what to do. Then he began, “Sir!”

Finally a terrible day came when there were no boys in his class. He came into the room, looked at the sea of girls, said, “Oh, nobody’s here to day!” , turned and went out without giving his lecture.
