Stuff you have done (that most people haven' t)

I failed 2/3 of the people who took a calculus class I was mis-assigned to teach. I didn’t realize there was a calculus class for non-engineering non-science majors until I was assigned to teach it, and then i was resentful of the fact that my calculus powers was held in such low esteem that i can only be trusted to teach it to people who will never ever use it again.
