[@Akayaofthemoon] That really sucks!  I thankfully never had any teachers blatantly choose favorites like that, but a few of them did have reputations for being abusive.  

Still, messing with them like that must have been pretty fun.  I wish I had been smart enough in school to mess with some of them like that, but sadly that wasn't me.  And yeah, I don't really have anything against teachers either but some of the ones I had were just abusive jerks.
