Yea Spike TV brought Ren & Stimpy back in 2003, it only lasted three episodes before being canceled. Also a lot of people don't know, the creator and voice of Ren, John Kirkfalusi, was fired by Nickelodeon in 1992 , three years after the show started airing. Then Nickelodeon produced the show themselves and the show would never be the same again. I don't know why but all these damn producers don't like John Ks style. John K is working on finishing the series on DVD so I really hope that works out.

EDIT: Also I just got "Clone High" never saw it one TV only lasted one season on MTV. Its actually hilarious I am defiantly a fan and recommend this show to anyone! I am working on getting the complete series of Beavis & Butthead, thanks for that one I totally forgot about them.
