Continuity mistake: In the scene where the mechanic is checking Hank's car, there is a guy in the car who is sitting on the right side with his hands on the wheel. The problem is the steering wheel is on the left side of the car. In the next shot the steering wheel and the guy return back to the left side of the truck.
Continuity mistake: Whilst Hank is talking about the price of popcorn at the movies Bobby & Connie come up to Hank and there is a blue poster next to Bobby of a woman holding a gun. In the next shot you can see the blue poster is now next to Hank despite a red & orange poster next to Hank in the previous shot of him.
Continuity mistake: When Hank & Peggy are discussing what film to see, Connie & Bobby were to the right of Peggy who is right next to the truck. In the next shot Hank & Peggy are getting in the truck and Bobby and Connie are already there. Yet we would have had to have seen them go behind or in front of Peggy to get into the truck.
Other mistake: In the episode, Hank's truck is destroyed when it gets stuck on the train tracks and a train smashes into it. Later on when Bobby is walking home by himself he finds the cover for the gear shift stick and puts it in his pocket. After a while Hank finds Bobby and Bobby gives him the cover and Hank puts it right on. Sounds fine. The only problem is that Hank has to screw the cover back onto the stick shift but doesn't have to remove any part of the previous stick. When the train hit the car, Bobby puts the cover right in his pocket and it would have had a bit of the stick left in it, as he had to screw it on. Its unlikely Bobby would have removed the bit of stick inside it because when we see him pick it up there is no part of the stick he would have been able to grip to unscrew it from the cover.
Continuity mistake: In past seasons, Hank's truck has obviously been shown as a 1992-era Ford Ranger,however in this episode it is shown as a 1980's-era Ranger.
Continuity mistake: The entire episode is about Hank being very attached to his current truck, and refusing to purchase a new one (until he has no choice). But in S4 E23 Hank tells Peggy "You know how much I want a new truck."
Answer: If you are talking about the "Thou shalt not do this, thou shalt not do that" song, I'm not sure if a song like that actually exists. Green Day, the guest voices on the episode, might have just been improvising to keep their appearance from being too obvious.
