After the teens' car breaks down, they go to a nearby house for help. The blonde girl puts her hand on her head as she becomes worried. Cut to a close-up and her hands are at her sides.
As the goofy student hands out flyers, he hands a pink flyer to the guy and a yellow one to the blonde girl. In the next shot, the guy has a yellow flyer and the blonde girl has a purple one. Thjey swap back again in the next shot.
When the goofy male student is passing out flyers advertising the big party, his friends come up to him and they begin a conversation. During this conversation, from shot to shot, the sun is sometimes shining down brightly and casting long shadows. Then suddenly it is much darker with minimal sun. Then back to intense sunshine again. This happens over and over again a dozen times in about a minutes time.
