I need web sites to get past school blockers!!!?

okay iknow alot of people say yea you shouldn't be doing that at school and that i have the chance of getting caught. well in our school they don't really care, even the teachers hate the blockers and they might have a good proxie every once in a while that they will tell us about. so like don't even tell me crapp about how i should be learning at school instead of on the internet and how i can save that for after school. hmm okay well i'm like an honors student with all a's and during seminar/homeroom it gets very boring so thats why i check my email....which is like facebook. so does anybody know any good proxie sites taht havne't been blocked, or any sites that send you emails that have new proxies that let you check facebook???please help!
