Continuity mistake: In the scene where Bill is trying to open the beer can with the back hoe, he rips up the pavement with it. As Hank sees the mess he gets in the machine and pushes the pavement back that Bill tore up. When Boomhauer comes along you can see his foot falls into the hole and gets stuck even though Hank pushed it back. Also if you look the soil Bill dug up has disappeared when Boomhauer comes along.
Continuity mistake: When Bobby & Peggy are about to steal Bill's flag, the truck drives right up against the flagpole. In the next shot Bobby is standing next to the flagpole and there are a few changes. The first is that the truck has a bit of space between the back of it and the pole, whilst the first shot it had no space in between (as it hits the pole). The other change is where the rope is knotted on the pole. In the first shot it was on the opposite side of where Peggy was standing. The next shot she has not moved but the rope is right next to Peggy facing her.
The Unbearable Blindness of Laying - S2-E11
Continuity mistake: When the family leaves for the basketball game Peggy brings the wrong foam finger (not the basketball one) so Hank turns around to get it. It shows him walking into the house, finding it but also finding what he thinks is laundry all over the floor. He also hears what he thinks is innocently the washer or dryer running. He follows the noise towards the kitchen, slowly opens the door to find his mother and Gary presumably having sex on the kitchen table. The problem here is that the kitchen has no door. From inside the kitchen in any episode it is never visible. I checked and further into this episode while opening presents it shows an entrance to the kitchen from the living area where Hank entered and there is no door on that side either. In truth it is an open doorway.
Continuity mistake: In earlier episodes, Luanne is very knowledgeable about cars. This is shown in "Shins of the Father" (Season 1). In "Jumpin' Crack Bass" (Season 2), she does repairs on Hank's truck - and Hank is known to be protective of his truck. As the series goes on, she becomes a stereotypical "dumb" promiscuous type, with no apparent expertise in cars.
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)
Hank and the Great Glass Elevator - S5-E11
Continuity mistake: After the banquet dinner where Bill sees Lenore, she comes to visit him at home. They are sitting down on the couch and when she's talking she has her hand on his chest and you can see there is a pen in Bill's right shirt pocket. Between shots she talks about stealing Bill away at the prom and in one quick shot the pen disappears and the next shot it returns. Also look at Lenore's hand in this scene. It goes from being next to his chest, away from his chest back to being on his chest.
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.
Square-Footed Monster - S13-E3
Continuity mistake: While Hank is at Arlen City Hall, asking about forms for a legal petition, the first clerk tells him that Hornsby has been dead for 11 years. The filled directory board is visible on the wall. However, when the second clerk says Hornsby has been dead for 18 years, the directory board is entirely blank.
Square-Footed Monster - S13-E3
Continuity mistake: When the four "day laborers" hop into Eric's pickup, then stop at Mrs. Dwyer's house, there is no doorknob on the door in the wide shot. However, a doorknob appears in the next closeup.
Square-Footed Monster - S13-E3
Continuity mistake: When the McMansion starts breaking apart, endangering the other homes, Dale's watch is on his left wrist, as usual. But when the neighbors arm themselves with tools, Dale's watch is on his right wrist (it's not a flipped shot), then it returns to his left in the next shot.
Square-Footed Monster - S13-E3
Continuity mistake: While the neighbors are tearing down the McMansion with their tools, when Hank chainsaws the door and kicks it in, Hank's watch suddenly vanishes from his wrist mid-shot.
Bystand Me - S10-E2
Continuity mistake: When Bobby encounters Harv at the Get In Get Out mini-mart, Harv's fingerless gloves vanish and reappear a few times until Bobby leaps into Dale's van. (00:11:00)
Orange You Sad I Did Say Banana? - S10-E6
Continuity mistake: At the end, when the guys are standing poolside holding their beers, none are wearing watches and all are barefoot, but after Kahn tells Hank his dream of an Olympic size pool, Hank and Dale are wearing watches and Kahn is wearing flip-flops. (00:20:30)
Orange You Sad I Did Say Banana? - S10-E6
Continuity mistake: While Ted and other Laotians are at Kahn's party, Kahn makes an offensive remark, and when Nguc begins to chastise Kahn the buttons on Nguc's shirt switch sides. (00:07:35)
Bystand Me - S10-E2
Continuity mistake: While Bobby's on the sign-up line, Dale complains it's not fair that only kids get paper routes, and Dale's watch vanishes from his left wrist, then reappears. The watch style also changes in the shots facing Dale. (00:03:20)
Continuity mistake: Peggy's shoes go from purple to white in one shot in Nancy's kitchen.
When Joseph Met Lori and Made Out with Her in the Janitor's Closet - S13-E23
Continuity mistake: After Dale pours cereal into a large bowl for cereal night extreme, he removes three boxes of cereal out of the cabinet and we see the empty shelf over the paper towels, but as Joseph stomps out of the kitchen there are boxes on that shelf. Then the appearence of at least one of the cereal boxes changes on the table. Also, funny how Dale pulls the mixer out of the large bowl and turns in on, but its cord is not plugged in.
Bills are Made to be Broken - S4-E3
Continuity mistake: When Hank and Bill are sitting on the hood of Bill's car and talking, one shot of the football field shows it to only be about 70 yards long between the end zones.
Continuity mistake: When Buck tells his employees about his plan for "service with a hug" there's a closeup of Hank. In the next shot a car pulls up in front of Strickland Propane, and in the exterior shot the front door knob is at the right side of the door, but in the next interior shot the door knob is still at the right side of that door, though it should be on the left side. (00:03:45)
