Another Quick Dispatch

NSLR says his teacher wants the kids to ask their parents for permission to see a PG-13 movie about tornados that she would like to screen in class. Of course, I say, and then I start to worry. I've never seen this movie, and maybe there is something really objectionable in it. So I check the IMDB page for "Twister," which informs me that the movie is "rated PG-13 for intense descriptions...of very bad weather." (ellipsis mine).
