Did you check LiveLeak? I can’t right now, because they are both blocked here at work.
The Chinese government has been blocking LiveLeak for quite a while now; Youtube since more recently.
They have a site called YouKu, which looks identical to Youtube, but, of course, is in Chinese, doesn’t relay any Youtube videos, and is strictly monitored. It does have a whole lot of interesting and very humorous videos, however, including many that tell on themselves.
