See Dick Continue to Run (2) - S2-E1
Other mistake: When Dennis Rodman sees Harry, Tommy, and Sally at the hardware store, he addresses all three by name and asks what they are doing on Earth. If he didn't previously know they were on Earth, then he couldn't have known they were going by those names, as they chose those names after arriving at Earth. Harry even mentioned in a later episode that the names Tommy, Dick, and Harry were chosen by chance when they saw the phrase "Every Tom, Dick, and Harry" written down.
Hotel Dick - S2-E3
Revealing mistake: Right at the beginning of the episode as the camera pans over to the doors of the movie theater you can see the actors playing the Solomons waiting for their cue to come bursting out of the doors as if they were running out of the theater.
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.
Other mistake: When Harry spits baby food on the baby (the camera lens in actuality) in retaliation for the baby spitting food on him and Tommy, Joseph Gordon-Levitt breaks character and laughs uncontrollably and looks at and gestures to off-screen crew members a couple times. (00:06:25)
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.
Proud Dick - S2-E13
Revealing mistake: When Harry lands in the yard, you can tell he lands on a crash mat, as the grass beneath him shuffles. (00:01:15)
Proud Dick - S2-E13
Other mistake: When Dick and Sally are playing with the cat toy in the kitchen, they make a lot of joyous noise while doing so. When the shot changes, we see Mary coming up the stairs to a completely silent home, and she can't seem to locate anyone until Harry pulls her into the closet. The kitchen is only a few feet away from the stairway, so not only should Dick and Sally's voices have still been very audible, but at the very least, Sally should have been in Mary's direct line of sight. (00:15:53 - 00:16:20)
Other mistake: When Dick is up in the tree fort, the aliens are looking at him through their hand binoculars, but the image is taken from the same height as Dick. However, since he is higher than they are, they would be seeing him at an angle. The view as seen would be impossible unless they were at the same height as he was.
Suggested correction: What the camera shows is for the audience. It's not meant to be a POV shot of what the three are seeing.
Character mistake: When Tommy walks into the flower shop, he tells the clerk that his sister is getting married. For the purpose of their mission, Sally, the sister in question, is actually supposed to be Tommy's aunt. (00:05:20)
Other mistake: When Dick is trying to get into the jewelry store, the clerk keeps trying to buzz him in. When that doesn't work because Dick doesn't understand to wait for the buzzer to finish before he tries opening the door, the clerk goes over to the door and unlocks the deadbolt and opens the door for him. If the door was locked by a deadbolt, then a buzzer wouldn't really do anything to unlock the door. (00:14:05 - 00:15:00)
Suggested correction: It's not a deadbolt. If it was they have retracting deadbolts.
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?
