The video you posted isn't funny. Bill Hicks has funny stuff, I would believe. Almost all comedians have good stuff. But that's not good stuff.

Just 2 days ago, I posted videos of a guy getting pied for 30 minutes straight. That's funny. You don't need intricate comedy for things to be funny (which Bill Hicks seems to believe). You just need pies and/or uncomprehensible screaming.
Check out the videos in the entertainment section.
