I have a little more time to think about this now. I'm thinking back to teachers who were clearly a little weird. For example, there was one who wore kind of really low-cut sweaters and would lean over in front of the boys' desks to check their work. You just can't do that shit to 14-year-olds and expect them to be able to stand up and read.
Then she'd do pushups in the corner while we were working... in the same low-cut shirt. And sometimes she'd make the boys do pushups.
There was more than one coach at my high school who got fired for going out to bars with students. One of them got caught making out with a girl.
The teacher I've thought about the most in terms of private life is Dr. Bollich, the theology teacher I talk so much about. He was fantastically intelligent, extremely open-minded for a high school religion teacher (most of them just teach fluffy "God loves you" crap over and over again with no real discussion), and so eccentric. He'd come in with weird clothes, huge alien heads, and other weird things for the daily lecture. In his office he had a huge Blue Bell Ice Cream tub, and he wouldn't let you leave until you asked for a scoop. Then when you asked for a scoop he'd say "Student... surely there's no ice cream in here. It's room temperature." Then he'd open it up and reveal that it was, of course, not full of ice cream. He also had Hindu god finger puppets. He gave me one.
I'd have loved to spend a day at his house. He also loved puns and wordplay, which I loved. His last name is pronounced "Bollick," and he'd say that his children's names are Meta and Hyper.
