I usually would sit near the back, and then complain about being unable to see the projector. XD I hate sitting in the front row, 'cuz you can't see all the fun stuff going on behind you. :P The people in the back always goof off, and that's what I do.
I remember just last year I had this supply teacher one day. I ended up talking to my friends about dirty things when we were supposed to be doing a work sheet. He moved me to the back of the class, around none of my friends. So, I just talked to the people he put me around. Eventually, he let me move back to my friends because he realized I was a disturbance no matter where he put me in the class.
