So in a serious fit of generosity, Funimation has released the entire series of Samurai Champloo... on YOUTUBE no less.
I can't really say a lot about this except thank the otaku gods for this blessing. Now if you're used to seeing it on Adult Swim, you may find it a bit hard to follow since it's subtitled but hell, if you're otaku you probably didn't like the dubbed version anyways.
Here's a little taste for you. The series itself can be found here.
