My first impression was the same, viz. she's simply a teen airhead. However the airheadedness conveyed is so contrived that it borders on sophistication. I know I maybe falling into the same trap that art critics sometimes get into when they praise an abstract painting and then find out that it was finger painted by a chimpanzee. I wonder if Jocelyne might be an alter ego of one of the more seriously insane folks at MSNBC, i.e. some of them are manic-depressive and Jocelyne comes into being during their manic phase. Another possibility is she's collecting data for a Ph.D. in psychology.
