I was watching a little bit of Adult Swim and Aqua Teen Hunger Force last night and decided afterward to dig up my old downloads of this series:

This was a potentially funny toon which took its parody just a little bit too far, and was noticed by Bill Cosby’s lawyers, who issued a Cease & Desist order. No more episodes were made. I can see why: if the creator hadn’t included Buck Naked Cosby and Cosbyette, Cosby himself would have allowed the parody to continue, because IMHO it was genuinely funny.
As it is, episodes (except the fifth, which I happen to have!) are still available for download. WARNING! NSFW!
