Continuity mistake: In the episode where porn videos are being sent to Hank, there is a close-up shot of a machine printing out address labels for Hank's house. These labels say 320 Rainey Street. However, in this episode, when Peggy is looking at the mail, all of their mail has 84 Rainey Street as their address. In several other episodes, the address is stated to be 123 Rainey Street.
Continuity mistake: In the episode we see the door to the boiler room (where Peggy's computer is) the door opens outwards into the hallway. Later in the episode she comes in to the room to check on some of her printings she was doing overnight. In this scene she opens it inwards. This wouldn't be possible as the door has a knob meaning it wouldn't be a two-way door.
Continuity mistake: When Hank takes Connie to the doctors, he is in the waiting room. After Connie and the doctor come out they open the two doors and stand in front of the doors. Towards the end of the scene as the doctor is about to leave them, they have all moved far a short distance from the left of the doors.
Continuity mistake: When Leanne first arrives, she kisses Luanne, and gets red lipstick marks on her. Later, when Leanne and Luanne are near the bathroom and Leanne says "I knew you would understand" (about Bill), she kisses Luanne, but there are no marks from her lipstick. Even if she mostly kissed Luanne's neck, at least part of some of the marks should show when Luanne turns to leave (after talking to Peggy).
Continuity mistake: As Hank is having his discussion with Cotton in the Casino you can see Cotton's red (playing) chips in front of him. In one shot Hank stands up and the angle shows Cotton from over Hank's shoulder and the red chips look black and badly damaged. The next shot from the same angle the chips are back to being red and completely fine.
Continuity mistake: When Cotton is trying to use the circular saw on the car dealer, the extension plug it's connected to gets disconnected around half way onto the alley road. The next shot its moved to just past the driveway, and the following shot it's now moved to about halfway down the driveway.
Continuity mistake: When Hank & the guys are talking about mooning from the glass elevator, Hank is positioned with his back next to the wall as he is sitting at the table. When Dale says his high school mooning was the best thing he ever did it. It then shows Hank and he says, "The vice principal gave you a week's detention" and is now sitting away from the wall with his back to a group of men in the opposite table.
Continuity mistake: When Peggy brings "Ol' Spanky" to class for the first time, the writing on the blackboard has quite a bit of space to the right of the blackboard. As she is telling of Joseph, the second blackboard is almost right next to the first blackboard and the first blackboard doesn't have the writing on it anymore.
Continuity mistake: As Coach Sauers is making them run up and down the stands you can see Bobby with all the mud on his face and body just reaching the bottom of the stand and then in the very next shot hes all of a sudden reaching the top of the stands with Joseph.
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. The next shot shows Peggy from behind still holding the tomato, and you can see there is not one fly around the tomato anymore.
Continuity mistake: On the plane whilst Bobby is watching the TV in front of him, you can see a man to the left of Bobby and an empty seat to Bobby's right. The seat arrangement looks to be like the middle row of seats where there is 3 seats instead of two. After the shot shows footage for the "Haiku" movie the shot changes to Bobby and the man sitting next to him but there is now no empty seat next to Bobby. It appears that he is now sitting at a window seat.
