De-Kahnstructing Henry - S3-E13
Continuity mistake: When Hank hands Minh the money for Bobby's lessons, he's wearing a watch on his left wrist, but when Kahn storms out of the house Hank's watch has vanished. (00:14:45)
De-Kahnstructing Henry - S3-E13
Continuity mistake: When Minh is taking out the garbage she trips over and starts punching the 3 bags she is carrying. You can see the bags are securely tied up at the top of the bags. The scene then goes to Hank and Peggy and you can hear Minh continue her punching on the garbage bags. As the shot goes back to Minh on the ground when Hank goes to see her 2 of the bags are now open and garbage is everywhere. Its unlikely she ripped open the bags herself whilst punching them as Hank ties them up at the top and there are no rips in the bag. They were also securely tightened to begin with. (00:15:25)
De-Kahnstructing Henry - S3-E13
Deliberate mistake: In the scene where Hank is mowing his and Minh's (Khan's wife) lawn he mows straight across from Minh's lawn to his own lawn. This would be impossible as in every episode including this episode (before and after this scene) there is a fence separating his house and Khan's house. It was likely removed to simplify Hank's going back and forth between the two ladies as they try to gain his affection with food and beer. (00:15:30 - 00:16:40)
De-Kahnstructing Henry - S3-E13
Continuity mistake: During the scene where Hank is talking to Kahn in the restaurant bathroom you can see a black rubbish bin below the hand dryer next to the entrance of the bathroom. About halfway into the scene Kahn starts looking into the mirror and the garbage bin has disappeared. Throughout the rest of the scene the bin never reappears. (00:18:20)
De-Kahnstructing Henry - S3-E13
Continuity mistake: When Hank and Kahn are together in Luly's men's room, there is a good view of the bathroom's walls, ceiling etc. Beside the door there are only six rows of tiles between the wall and floor, there is no molding at the top of the wall, and so on. A bit later, there are at least seven rows of tiles, and suddenly there is crown molding between the ceiling and wall, and so forth. (00:19:00)
De-Kahnstructing Henry - S3-E13
Continuity mistake: When Hank walks into Luly's men's room, Hank's watch is on his left wrist, Kahn's hair is parted on his right side, the stalls are to Hank's right and urinals to Hank's left (same side as his watch). Some of the following shots show them in the mirror's reflection. After Kahn says, "Times hard, but Minh's a fighter, they be ok," it cuts to a particularly odd shot of Hank and Kahn. The entire bathroom we see behind them is backwards, as if it's the mirror's reflection shot (stalls and urinals on the opposite sides), but Hank's and Kahn's watch and hair part are on the correct sides, which is not possible if it were a reflection. (00:19:10)
De-Kahnstructing Henry - S3-E13
Continuity mistake: When Minh is sitting on the ground surrounded by trash bags, the door is visible behind her, minus one doorknob. By the time Peggy sends Hank to the rescue, the doorknob reappears.
De-Kahnstructing Henry - S3-E13
Continuity mistake: When Kahn drives up the alley, passing Hank, Bill, Dale and Boomhauer drinking beer, there are no door handles on either the front or back door in the close-up of his car, yet, oddly enough they appear later on in the wideshot.
De-Kahnstructing Henry - S3-E13
Continuity mistake: When Peggy is returning the blue bowl to Minh she is holding the bowl and is outside the glass sliding door at Khan's house. The shot then shows Minh and goes back to Peggy where she is now standing inside the house and didn't move at all during the shot of Minh.
De-Kahnstructing Henry - S3-E13
Continuity mistake: When Kahn comes home after getting his promotion, Minh has the fridge door open. Between shots almost all the items in the door disappear, and the cans inside the fridge change colour.
The Wedding of Bobby Hill - S3-E14
Deliberate mistake: As Luanne is putting the dirt into Bobby's fruit pie you can see she rips open a large part of the packet. Yet in the next scene when Bobby is about to eat the pie there is no sign of where Luanne ripped the packet. Its likely this was deliberate as the joke in the scene was Bobby and Luanne's constant attempts to get back at each other, if they had left the large hole its likely Bobby would have not fallen for Luanne's prank.
The Wedding of Bobby Hill - S3-E14
Continuity mistake: During the scene where Peggy and Hank are enjoying a spa, Hank fills up the champagne glasses with beer. He stops pouring a bit before the top of the glasses and there is very little foam on the top. In the very next shot both their glasses have foam overflowing from it.
The Wedding of Bobby Hill - S3-E14
Revealing mistake: During Rad's haircut from Luanne, there is a shot that shows the both of them in the mirror. You can see both their reflections and the room in the mirror but the objects on the counter in front of Rad have no reflection.
The Wedding of Bobby Hill - S3-E14
Continuity mistake: As Bobby visits Connie and is at her window he lays his hands on the window sill. The next shot they are back by his side and they keep alternating back and forth even though he never moves them between shots. At the end of the scene Connie shuts the window smoothly even though his fingers were still there in the shot before.
Continuity mistake: When Herrera is swinging the fire in the trick for Nancy's birthday party, you can see Dale, Nancy and John Redcorn are at their tables sitting near the stage. In some of the following shots you can see they are further back, towards Hank and Peggy.
Continuity mistake: In the shot where Hank is using the paint roller on Bobby's wall, where he has it positioned it is around level with his head. When the shot changes to showing his face the roller has moved considerably higher out of position from his face.
Continuity mistake: After the dolphin encounter, Hank has water dripping his face. In the very next shot when the camera guy is talking to him and Luanne, the water suddenly stops dripping. The shots were too quick for it to stop that suddenly.
Continuity mistake: Whilst Hank is in the hardware store, there is a clock behind the clerk on the shelf. It changes from 7pm to 5pm between the later shots in the scene.
Continuity mistake: As Bobby is complaining about the capers, we can see there is almost a full jar of them. After Luanne shows the old clothes she is wearing to work, the jar is near empty. Later in the scene the jar returns to near full again.
Escape from Party Island - S3-E17
Continuity mistake: Before Hank & the old ladies depart Arlen, the guys (Bill, Dale and Boomhauer) are in the alley behind the van. The next shot they are against the wall and the van is opposite them in the alley.
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.
