Once upon a time long ago in a far-away land there lived a man named Dr. Galen Baril. Now Dr. Baril was not the pleasant sort. Despite the fact he had a Phd in social psychology he wasn't very skilled at being understanding of others. He would revel in torturing his poor psych stats students. Every week he would have a quiz that would take 30 mins to finish, but if that wasn't bad enough he insisted on squeezing the whole thing onto one side of a 5th of a piece of paper and *all* work had to be done in the spaces provided. He would put trick questions on the quizes and then ridicule the class for not getting it right. If a student had a question he would first mock the student who had the audacity to not understand his oh so brilliant and coherent lectures and then complain afterwards about how he just didn't understand why the students didn't understand. Obviously there couldn't be anything wrong with the way he was lecturing! Halfway through the semester he decided that the grades weren't as good as he wanted them to be. It must be because people weren't doing their homework! So he made a little change to the normal class procedure. Now students must make a copy of their completed homework the day to hand in at the beginning of class on the day he decided to go over the problems. While there would be no reward for doing your homework completely there would be a deduction from your grade if it wasn't completed to his satisfaction (Apparently in his many years of studying Psychology Dr. Baril had managed to miss or forget the concept of positive reinforcement.)
You're probably wondering why after so many years of training in the field of psychology one could have such a misunderstanding of how people work. Well I'll tell you why: It's just hard to be a nice person when you have a giant floppy penis for a head!!!
