My high school Biology teacher plays Portal, Duke Nukem, Wolfenstein, CoD AND Mass Effect And she let us watch funny youtube videos in class, and has a long lineage to cats who have caught fire. Checkmate
That's one awesome teacher. I once had an English professor in my first year of college who turned out to be an Axel fangirl. So being the Axel fanboy that I am, I actually forgave her for all the crappy assignments she made us do.
As soon as I find a teacher who shares my love for the cast of VividRed Operation, especially Aoi Futaba, I'll do my best to get an A+ in that class.
