This happens when Amanda goes to the interview to meet the Buttkiss's. After Diane makes Amanda spit out her first piece of gum, she says "Other gum" Before the camera switches angles, Amanda's hair was all over the place because she had just taken off her hat. Once she turns around, however, her hair was all in place again. Then she goes on to spit out her "other gum" and marches up the stairs to the front door. This bothered me every time I saw the movie.
