Yes, I suppose that our high school PE teacher might also remember that. That would be Mr. Moran, a name which, in terms of pronunciation may sound sort of like Moron, but with emphasis on the second syllable. Mr. Moran might have been somewhat of a blusterer, I don't remember anything specific, starts by putting us through our calisthenics routine and blowing his whistle sometimes.
Coincidentally, our next door neighbor here in Florida was also a Mr. Moran, but from Honduras, although he had to leave and sell his house due to his moronic behavior. But that would be a completely different story. I don't imagine there would be any connection there.
