I discovered a pretty funny video called "Charlie the Unicorn". After watching it I Googled for the maker "Jason Steele" and found another good one, "Spatula Madness". Great South Parkish animation and stories with that required sense of nihilism.
Found some fan art too. On their site filmcow.net there are some other videos as well, even some live-action stuff, but perhaps it's not as good. If Jason Steele ends up big and famous, Charlie the Unicorn could become cult stuff.
