Continuity mistake: When Mr. Clark drives his car to the inner city school, he asks a punk where the faculty parking is. The punk points to the parking lot and as John drives away all of his tires are blown out by road spikes (he goes through a wrong way road). When he gets out of the car, notice that some of his tires have mysteriously reinflated themselves.
Richard Clark: I've never been very good with relationships. In fact, most of mine ended with "Hey, what are you doing in bed with that other woman?" And that was me talking.
