Me cousin is the only bloke I ever knew, what said he didn't want his mother to ever call him "doctor" after he earned his Ph.D. I say even if Dr. Matt has his Ph.D. in wallaby forking, we should call him doctor.
Me lady friend, what actually knows Matt Kay and actually taught with him, says he's all right, and they never forked, either, and he was a good teacher. But this isn't about Matt's teaching, is it? Is he a competent administrator at CMU? He is, by definition, if he's still on their payroll. The bloke what started all this commotion is no longer on the payroll.
Who knows ten graduates of the course at CMU? I mean, well enough to have professionally judged their competence in the classroom? Who knows ten graduates who have judged the course at CMU?
