Oh, this brings back a memory! In 5th grade, the girls got a note that they were going to the auditorium to see this film while we were stuck in class. As the Paul McCartney song "Girls' School" says, "they put the papers on the window"! I remember being jealous that the girls got their own movie.
When I asked one of the girls what the movie was about, I got a very terse "none of your business"! This would make a great short to riff -- although it might be safer for Bridget and Mary Jo to do it!
