Robert: All right, Timmy, let's behave ourself. We're here to teach traffic school. "Yeah, right. Okay, let's see who can answer this. When you're behind another vehicle, what is the proper following distance, Frank?"
Frank: Well, if the guy's going really slow, I like to be right on his butt. So if he looks back, he can read my lips.
Robert: No, Dad. It is one car length per 10 miles of speed. "Yeah, remind me to never drive with you, you crazy old bastard."
Frank: How's that?
