Continuity mistake: When Ms. Dubcek is showing the Solomons the attic apartment in the pilot episode, they enter (and she later exits) through what is Dick's bedroom in all subsequent episodes. Additionally the staircase at the back of the living room that serves as an entry point is completely missing.
Continuity mistake: As Harry is leaving the party he is dry despite having just been in the shower fully clothed.
Continuity mistake: In the scene where Harry and Tommy are sitting in the living room, Sally comes by with a drink for Tommy and the shot changes when she is behind Harry and walking towards Tommy. But in that next shot, Tommy is already holding the drink.
Continuity mistake: When Nina asks when Dick's birthday, is the papers on the back of her clipboard change position between shots.
Dick Is From Mars, Sally Is From Venus - S1-E4
Continuity mistake: In this episode Dick decides that Tommy has to go to school, but in 1-2 "Post Nasal Dick" Tommy already goes to school.
Suggested correction: That's just because these episodes were aired out of order of their production. "Dick Is From Mars, Sally Is From Venus" was the 2nd episode produced (production code 102) while "Post Nasal Dick" was the 5th episode produced (production code 105).
Continuity mistake: The dog that Harry brings home suddenly has a collar after Dick sets him down on the table. (00:02:40)
Continuity mistake: Mrs. Dubcek says that she doesn't allow dogs because she is allergic to dogs, but in a later episode she claims that she doesn't allow dogs because she has 6 cats buried in the back yard.
Continuity mistake: When the dog is on the table, the book on the right of the table changes position between shots without anyone touching it.
Continuity mistake: In the beginning when Dick is talking to Sally and Harry about Mary, the position of his tie changes after he says "what's the point."
Continuity mistake: When Dick gets out of the chair to talk to Tommy, his newspaper is on the chair cushion. Later, it's on top of the pillow.
Continuity mistake: When the baby Is in the ball pit you can see that he is at the edge. When they show him again he is in the middle, the last time they show him he is at the edge again.
Dick and the Single Girl - S2-E24
Continuity mistake: When Sonja takes Dick's belt, she has it in her right hand, away from Dick. In the next few shots, Sonja no longer has the belt, but it is back around Dick's pants. Yet the next shot (at the door), it's in Dick's hand. (00:16:30)
A Nightmare on Dick Street (1) - S2-E25
Continuity mistake: In 1-2: "Post Nasal Dick", Harry has a dream about Martha Stewart. But in this episode they panic because they dream and have nightmares and don't know what they are. Shouldn't Harry have panicked when he dreamed about Martha Stewart?
Scaredy Dick - S3-E5
Continuity mistake: Before the offscreen trick-or-treater starts throwing eggs into Mary's house, you can see she already has egg stains on her jacket from previous takes. (00:17:40)
Continuity mistake: When everyone is in the living kitchen, Tommy ends up getting 2 darts stuck into the dartboard. When Harry throws the remote, the 2nd dart is missing. But it's back in the wide shots after Jennifer comes in. Later, when Tommy throws another dart, that 3rd one is seen, but not the 2nd one.
Continuity mistake: When Jennifer comes into work the next day after her dinner date with Dick, her face is covered in hives from an allergic reaction. Later when Dick interrupts her choral group, the hives on her face have disappeared. She and Dick are wearing the same clothes in both scenes, so she couldn't have overcome such a reaction in such a short amount of time. (00:12:30 - 00:15:00)
Continuity mistake: During a conversation between Sally, Mary and Nina about posing for "Playpen" magazine, Mary's glasses are on one second, and then off the next. This mistake repeats twice in thirty seconds. They're nowhere to be seen otherwise. (00:13:30)
Continuity mistake: The bottle of orange soda on the breakfast tray Dick tries to bring to Mary changes to a bottle of alcohol (Jack Daniel's I believe) when he sets it down. It later changes back into the bottle of orange soda.
Continuity mistake: In the scene where Dick is buying a laptop, you can see that while the computer is on his lap, it is not really on. (00:06:40)
Continuity mistake: Dick hands Nina a box full of dishes and asks for them to be cleaned. She then drops the box on the ground where it lands upright. All of the dishes remain in the box. The next time it's seen a few seconds later, it's suddenly on its side with dishes scattered across the floor. None of the characters touch it and there is no sound indicating that it magically tipped over by itself.
