That would, I think, be the late 'Jakey Hogg.' He taught maths at St Ninian's when I was there and I was supposed to go to the staff room for 3 of the best from him at lunchtime (difficult, as I caught the bus home for lunch) and I managed to avoid it with a variety of excuses for the last 2 or 3 weeks of the term and, the next term, he was off ill.
