Other: On outside shots the front door is on the extreme right. Shots from inside the house show the living room on the left and the door in a central position.

Other: On the exterior front shots of the house you see the front door with three vertical windows. But on the interior shots it is just one window.

Audio problem: Season 8, Episode "Wish Boned": When Doug found Arthur after his running away and they were about to board the plane to St. Louis, Arthur's voice sounds fuzzy because the new t-shirt he's wearing is covering the microphone on his chest.

Continuity: In many episodes, scenes are shot on the front porch. It is often shown as a large porch that spans a great deal of the front of the house. But shots of the house exterior from a distance show a small set of stairs with very little space near the door. This isn't a porch on the back of the house as it has been shown to only be door to a small yard.

Continuity: The Home Cheapo Series: In the scene where Deacon, Kelly, Kerri and Doug are silently debating over who will pay the bill, Doug pushes the bill over to Deacon and it lands diagonally in front of Deacon's beer. In the next shot the bill has changed positions without being touched.

Other: In front shots of the house you see that the garage is in the front and opens to the street, but in inside shots the garage is in the back and also opens to the backside.

Revealing: When they first drive to their class, we see the street lights behind them. When Carrie pulls over to pick up Spence, she turns the steering wheel, but the lights in the back don't turn.

Continuity: After Spence suffers from his allergic reaction to peanuts he's seen lying on the couch. Doug then says something to the effect of having to scrape Spence's lunch off the fence, indicating that he threw up. But the allergic reaction took place before they got to the lunch.

Continuity: When Spence realises he's eating peanuts, he steps behind the bench he was sitting on, but in the next shot he is in the front of the bench.

Continuity: When Carrie fixes this super-huge sandwich for Doug's football buddies, she tells him to stay away from one end, because she used bad meat there. However, the episode ends with Carrie and Doug eating the sandwich from either end.

Continuity: In the flashbacks in this episode, Carrie and Doug meet for the first time in a bar, but in the episode "Road Rayge", Carrie mentions a junior high school dance where Doug asked her to dance.

Continuity: In the scene where Arthur is on the phone with PBS to complain about getting a "Civil War Series" box set, the actual set of tapes changes drastically. When it's on the table and when Carrie brings it over to the counter its a pretty large, has an American flag motif, and says "Civil War" across the top. When it cuts back to it sitting on the counter its a much smaller box with a plain design and says "Civil War" along the bottom. It's obviously a different set, not just the camera angle.

Continuity: When Carrie takes Doug into the back yard to yell at him, after she is done swinging at him, she puts her hand up to her chin. First it's her left, then right. It changes between shots. Each time the camera goes back to her it happens.

Continuity: Carrie tells the preacher that she and Doug met at a bar. When she hears the lie about her falling on Doug as a kid, she believes it and acts as if that was their only meeting before the bar. But in the episode "Road Rayge", she mentioned a junior high school dance where Doug asked her to dance.

Continuity: Doug made a blue snowcone in the kitchen and then goes into the living room to talk to Arthur. When he crosses the door in to the living room, the initially full snow cone is now almost gone.

Continuity: When Carrie finds Tina, she mentions the "stuff" that Tina listens to at work, and Tina tells her that it's salsa. We know from previous episodes that Carrie likes salsa dancing, so shouldn't she know salsa music?

Revealing: After Arthur tries to use his two empty nasal sprays, he crazily picks up the garbage can and dumps the garbage onto the kitchen floor, to find another nasal spray, tossed out earlier. He searches through the mess and finally finds it, but the white bottle of nasal spray wasn't amongst the garbage that fell out of the can, it was strategically placed off to the left, behind the can (when it was still on the floor), so Jerry Stiller (Arthur) would easily find it.

Continuity: In this flashback episode, when Doug is shaving his moustache and talking to Deacon by his locker at IPS, Danny Hefferman's name can be seen on a locker. At this time Danny was not working at IPS.

Continuity: In the scene where Doug's father is shutting off the alarm, he does not enter 2965. We know this is the proper code, because it is Doug's birthday, and it worked when he entered it. It looks like he maybe enters 1459.
