When Burt leaves the Tate house, he slaps a bumper sticker on the door. When he does so, it is almost horizontal. The scene switches to Jessica and Dr. Posner. But when the scene switches to Leslie as she enters the Tate house, the bumper sticker is now at a 45 degree angle.
The announcer says if Billy breaks up with Leslie, "how would this affect his grades?" Leslie was no longer his teacher, so it wouldn't affect his grades at all.
When Danny finds out Burt is running for sheriff, Danny pleads with Burt to be his deputy. Burt explains to Danny that he has to be trained, but Burt has no experience, either.
