Corrected entry: After Summer and her friends perform their "skit," the crowd is heard clapping, making whoops and whistling. However when the camera shows the crowd of kids, they are clapping but nobody is whooping or whistling. Several kids are chewing gum and one girl is laughing, the rest have their mouths shut. There are no fingers up to mouths to produce whistling sounds from the crowd.

Correction: The whole audience isn't shown in the camera's view. If you look carefully, you can tell there are more kids off to the sides of the auditorium. They could have been the ones who were whooping and clapping.
