Haha, that's a good one. The last shot of Arnie on a loop is pure comedy. There used to be a legit video with the song above, where it spliced footage from the film and lines of dialogue into the rap - shit was gold - don't know what happened to it.
Yeah, I remember that! I'm guessing maybe it became popular enough that it caught the attention of Fox or something, and the kibosh was put on.
If that's the case, they apparently haven't unearthed it's unofficial sequel yet: http://www.youtube.com/watch?v=P1V12iV_PHI
