We have 4 copies of this on VHS, and we used to watch it every couple months. We had our own MSTK sountrack to it. I think I know this whole movie by heart.

holy crap, R.O.T.O.R! we've had this VHS for years too. it is unspeakably brilliant. highlights include the skunk-haired lesbian scientist and the line "once you go red, you never get out of bed!" delivered by an ostensibly Native American extra in a bar.
