Ms. Donegan - Algebra. Two things stand out in particular: (1) She always referred to us by the first three letters of our last name, so I was Mr. H-A-R. (2) Whenever she asked a student a question in class and there was any pause, she would say,"Mr./Ms. _-_-_, do you comprehend the situation?"
Mr. Tabor Biology - from Day 1 he iterated, "Labor with Tabor, he'll be your good neighbor." He literally did have our class and others labor in the Lane garden during that first semester picking weeds, planting seeds, watering and removing debris.
Mr. Childs Economics - He would yawn literally every 5 minutes as he expressed genuises needed only four hours of sleep. The lenses of his glasses were so thick you could barely see his eyes. Yet he would get a little ticked when he would ask a question and the students in that direction would look at one another like, "To whom was he speaking?"
These are my top three. As others have stated, our teachers had their quirks, idiosyncrasies and mannerisms, some of which we remember so many years later. Yet they did have a deep commitment to teaching and did so with excellence. Go Lane go!
