What is a good site to unblock sites at school?

My school has blocked sites like Myspace,YouTube,YTMND, and Somethingawful. They already blocked every letter tunnel like ztunnel and sites with proxy and unblock in the url. Any help?
P.S. They blocked milkfat716 as well.

Here are a few you can use:
