Of course, my first response was "Men's Courses generally lead to pissy little flamewars on SCA-East." But then my belief that you could chart men's menstrual cycles by following SCA-East is well known. (Theory says it's about 6 weeks.)

The other day I was waiting for Juergen to come out of a store and the lady in the car beside us said to her man companion, "What, are you PMSing today?" I was greatly amused.
