Proxy sites not blocked by school?

I need some proxy websites that will most likely not be blocked by the school system. I have a speech site today and i was supposed to show the class and I have to hang around outside .. Help?

I used to use these proxies at my school: www.studyhard.co.nr www.school4sale.co.cc www.school4sale.hu.tl www.schoolissucks.co.cc www.school4retarded.co.nr www.studyhard.tk
