As everyone knows, MIT’s President Paul Gray was very fond of students. One day a student defecated on his desk in protest of a sizeable tuition hike, and President Gray’s secretary caught him in delicto flagranti. She made a horrible fuss about the incident and ended up calling the police. But President Gray, who was also summoned to his office by the distraught secretary, pleaded with the police officers to drop the charges against the trembling student: “All the doors and all the corridors at MIT look so much alike that the poor chap confused my office and the men’s room couple of doors down the corridor!” Everyone laughed. Police officers dropped the charges, and the student cleaned up the mess on his own accord. Of course, President Gray had to dismiss his secretary, who had no understanding whatsoever for student pranks.
