thatames (sorry, "Kate" at
Market My Monkey) just directed me to the
original ending of Little Shop of Horrors (scroll down). It's pretty creepy and depressing. Sci-fi stories about intelligent, man-eating plants have always given me the heebie-jeebies (I blame my fifth grade teacher and the fact that he forced us to watch The Day of the Triffids - eeeeeeeeeeeeeeeeeeee!). I found the original happy ending creepy enough.
Still, it is pretty cool. I just won't be walking through any greenhouses any time soon.
