Continuity: As the popular kids are speeding past the school security guard, notice the last car a black pick up truck. There are six kids in the back of the truck. In the very next shot you can see there are only two kids in the back. Although one of the kids was crouched in front of the kids that were standing up and might have been obscured from view, the other three were sitting in plain view and have disappeared.

Revealing: Just before the security guard smashes his car into the oncoming car, you can see he has been replaced by an stunt dummy.
