Senior chemistry teacher, really fun and did lots of crazy stuff. Once blew out all the second story windows and caught the curtains on fire when exploding sodium in the courtyard. After that he used less sodium.

My little group of friends and I were rejects from the majority of kids but we had a lovely english teacher who let us sit in her room at lunch time for the last few years of high school. We often chatted and when we graduated she gave us each a gift that we all treasured. Fast forward a decade or so and one of my group ran into her at his choir - she didn't recognise him and after a few months he approached her and said who he was - she totally didn't remember any of us at all!! With some prompting she had a vague recollection. Sort of spoiled the memory lol.
