(This takes place after they are at the restraunt and while they are on the highway thinking of what they should say they invented.)

As you know, Romie and Michelle want to impress there high school class by telling them they invented postets. When Michelle gets mad at Romie for saying she was more of an inventor Romie pulls over to the side of the road. They get in a big fight and when they get back in the car, you can see Michelle put on her seat belt. I'm not sure about this but I think they get a close up on Romie and then they get the screen so you can see both of them in the car again. If you look at Michelle, you can see her trying to get her seat belt on but it is like jammed so she just throws it back. I guess either she took off her seat belt and tried to put it back on again or that seat belt just un-buckled itself! I know this wasn't that big of a slip-up but it was still something!
