Usavich is a strange little cartoon from Japan. Let me see if I can summarize: two rabbits are imprisoned in Russian jail. One is dumb and gentle, the other is placid unless provoked, and then he becomes ultraviolent. There's also a transvestite chick and a frog, and there's no dialog. The whole thing is as bizarre as any other cartoon you haven't watched yet, and after a few episodes, it all makes perfect sense.

As Jim Flanagan (from whose del.icio.us feed I got the link) says,

Damn odd. Compellingly so.

It's a very well-done cartoon. The official site has high-quality video, but only half the episodes are there. Automatic Daddy has collected all of the YouTube clips for your convenience.
