Continuity: After the frantic phone call from the hospital, Hank rushes to the emergency room. In the hallway there are two doors, the one to his left says "Consultation" whilst the one to his right says "Examination". He uses his left hand to open the door and in the next shot you can see the door now says "Examination" and "Consultation" on the opposite door.

Continuity: When we see Bobby talking to Hank about the allergy test there are lots of black marks (dots for the allergy test) on Bobby's back and one red circle around one of them. As Hank is looking at them there is a shot from behind Bobby and the red circle has gone.

Continuity: When Hank goes to Bobby's class for "environmental court" and is sworn in, you see Bobby sitting at a large desk and to the right there is nothing next to it. The next shot there are now a few empty desks next to the large desk.

Continuity: When Hank, Dale & Bill go to the quarry to get the car, they use a tow truck to try and pull it up. If you look at the tow truck you can see it is a red color. Later on when the protesters come and are sitting in a circle and singing the tow truck is now orange. It stays orange for the rest of the scene.

Continuity: As Hank tells Bill & Dale that they are going to drain the quarry (whilst in Dale's basement) and Dale lets his burning cigarette drop. Dale & Bill start to freak out and it goes to a wide shot of the three of them & the cigarette Dale dropped is not on the ground anymore.
