Continuity mistake: After Hank calls Bobby into the room to talk about the woman's magazine Peggy discovered, you can see Peggy's hair is a little messed but nothing in it. A few shots after Hank asks Bobby about making the turkey there is a close up shot of Peggy and she has a few stains in her hair which disappear in the next shot. The stains look very similar to the ones she gets a little later on when she falls on the turkey.
Continuity mistake: The door to the slaughterhouse (which Luanne blocks with the barrel) changes configurations between shots. When Trip is trying to get in, the exterior is blue with a doorknob. After Peggy busts in, it is white with a pushbar across the middle. The interior is white with a pushbar in all shots.

Continuity mistake: During the scene where Peggy still finds insects over the tomatoes, she goes to show Hank one of the tomatoes. As she is showing the tomato it has around six or seven flies buzzing around it.

Continuity mistake: Peggy's shoes go from purple to white in one shot in Nancy's kitchen.
Continuity mistake: At the end when Laoma is crying and hugging Bill, the tears on her face are on her cheeks. As she asks, "Wait, Astronaut who?" the tears are now just found near her eyes. As Bill explains, she has her hands on his shoulders. She then turns and the tears are not even in her eyes now.
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.
