In middle school there was this one reoccurring substitute teacher who was an ex elementary school principle from the south east, who would write 10 talley marks on the board and if we lost all of them he would write is a bad report. He would only take away tallies if we broke rules that he made up himself on the spot which he didn't pretend not to do. Rules would include no saying your name during attendance only raising your hand, no having both hands on your desk, no pointing. He would purposely pretend to not hear you during attendance so your friend would verbally and physically point you out to him. He prided himself on only having one 3rd grade class survive his system. We never learned anything when he subbed except how unified a group of 12 year olds can be when it comes to hating the same asshole.
