For me it's gotta be my entire year 9 math class. Our teacher was a bit of a knobhead for the entire year and was so rude to the guys for no reason. I've got so many stories from that class but the one that stands out the most is when one of the guys in my class was 'turning' the projector on and off continuously by aiming his calculator up to it when in reality he just had the remote under the table that he was using. Our teacher believed it so much that he confiscated his calculator from him. Then the guy would start handing the actual remote to the rest of his friends and they'd be doing the same thing. By the end of the class I think he ended up confiscating 6 or 7 different calculators and wouldn't give it back to them. Seriously how thick in the head could he get??
