Comparison between the shortened version of "Who's Stupid Now?", taken from the US DVD by Paramount, and the uncut version, taken from the German DVD by Turbine Classics.

The differences:

3 cuts = 1 minute and 2 seconds

The Ren & Stimpy Show is one of the most over the edge cartoon shows ever. So it's no surprise that Nickelodeon US - similar to Disney - reacted to the feedback of the audience and made a few cuts. On top of that, later broadcasts on Spike TV contained further alterations. More cuts were made and, if required, some scenes had a higher frames per second rate in order to reach the regular length for syndication. These versions are the available ones on the so-called "uncut" US-DVDs by Paramount.

Surprisingly enough, the German broadcasts back in the 90s were amlmost uncut, only a few scenes with too explicite footage were removed.

For the uncut box the comparisons have been made with, Turbine Germany used the cut (but restored) US masters and the original German versions in order to put the longest versions possible on the German DVD set. Missing scenes in the US Versions have been filled with the German version (including the German dub), missing scenes in the German versions have been filled with the US Version (and they got subtitled in German, if necessary). The result is the longest version available of every single episode.

The complete scene before the intro is missing. A stage with an audience in front of it can be seen and some comments from the off that Hollywood's biggest secret will be unveiled. It is the dog everybody was waiting for, "Ren Hoëk". The curtain is moved aside and Ren enters the stage completely veiled. He goes to the front of the stage and tears his clothes off, saying that that was for his fans. A chubby and naked Ren can be seen and the audience applauds again. THen the picture freezes and Ren can be heard talking. He says that his days as a weak chihuaha are over and that he is now bigger than life but that he should talk about the past first. Then the intro starts.
