One way to make your presence known in a class:
Almost pass out while your regularly unruly class is completely silent and working on a huge test and have your teacher have to escort you out of the room and almost into the women's' lavatories and then have to call the librarian to come pick you up and take you the nurses office and then when they ask what's wrong you say " Don't worry because this freaky thing happens to me every once in a while and I have no idea why!" And then your parent has to pick you up and then everyone eventually finds out and it becomes completely moritfying.
And how, may you ask, do I know this?
Oh yeah, because that's what I went through today....
