Three Coaches & a Bobby - S3-E12
Continuity mistake: When Hank sees Coach Sauer driving his car on the field, you can see Sauer's car has a red front bumper. When we see the front bumper again a few shots later it is grey. (00:15:30)
Three Coaches & a Bobby - S3-E12
Continuity mistake: Before Peggy leaves the soccer mums and goes to watch football again, the woman in the green sweater is holding a coffee cup that is of a pale brown color. When the shot goes to a close up of her talking, the color is now red. The next time you see her holding the cup, it's gone back to being a pale brown color. (00:18:15)
Three Coaches & a Bobby - S3-E12

De-Kahnstructing Henry - S3-E13
Continuity mistake: After Kahn shows the guys his new car, he shows off his new sunroof too. Later when Kahn goes to Strickland propane and in the establishing shot it shows his car outside the store and the sunroof is no longer on his car and no marks to indicate its just closed. (00:01:00 - 00:02:00)
De-Kahnstructing Henry - S3-E13
Continuity mistake: When Kahn parks the car in the garage you can see the driver's window is clear. A few shots later we see the window is now frosted. (00:01:35)
De-Kahnstructing Henry - S3-E13
Continuity mistake: As Kahn is ringing the bell in Strickland Propane trying to get some attention the bell is right next to his hands. When Hank comes out there is a wide shot and the bell is now a short distance from Kahn's hand. The counter also changes size as you can see where it ends just to the left of Kahn but in the wide shot the counter runs from wall to wall. (00:02:00)
De-Kahnstructing Henry - S3-E13
Continuity mistake: At Strickland Propane, when Kahn hands Hank his propane tank, it is set down on the counter right beside the bell. However, in the shots facing Kahn, the bell is directly in front of him, but the propane tank is nowhere to be seen. Additionally, during this scene note the difference in the ceiling height in relation to the wall boards and the doorway behind Hank. (00:02:20)
De-Kahnstructing Henry - S3-E13
Continuity mistake: As Kahn is putting the golf club away after Hank has just used it there is a groove in the locker to support the club. Kahn seems to place the club horizontally in the locker no where near the groove and to the left of it. The next shot its now sitting in the groove vertically. (00:05:05)
De-Kahnstructing Henry - S3-E13
Continuity mistake: As Kahn breaks the ceramic radio panda at the garage sale there are about 3 people behind him. He then starts to tell everyone to leave and then there is an aerial shot and the 3 people that were behind him have disappeared even though no one moved whilst he was shouting. (00:12:30)
De-Kahnstructing Henry - S3-E13

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
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
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
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.
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.
