Continuity mistake: In all episodes, shots and zooms from outside onto Mindy's apartment show a different front of windows than from the inside. That includes size (width vs. height), glass patterns and coloring, and distance between single windows. Even the glass patterns seen from outside occasionally change from episode to episode. From the inside there is a door (to the staircase) between the small window to the right and the bow-front. From the outside, space for a door or a staircase is completely missing.
Visible crew/equipment: When Mork and Mindy are walking away from the lake after they first meet, there is a set of 8 lights in two rows of four in the background.
Revealing mistake: Before the officer comes in, Mork is 'saving' eggs. When Mork puts an egg under the cushion of the first bar stool, the cushion's underside is already wet or sticky with what looks like egg.
Continuity mistake: At the beginning of the court scene, before Mindy and Fred enter, on the close up shot of Mork, there is someone in a suit standing behind him (looks like Fred). In the long shots, no one is behind him.
Mork in Love - S1-E5
Continuity mistake: In the scene where Mindy shows Mork the differences between herself and the mannequin Dolly, Dolly is in a different position in every shot. Her legs are sticking straight out when she first 'sits' down, then bent down, then straight out again, then closer together and the left shoe is on backwards, then her right shoe is backwards, then she's tilted to the left and finally she's sitting straight up.
Snowflakes Keep Dancing On My Head (a/k/a Sky Flakes Keep Falling On My Head) - S1-E17
Revealing mistake: There are several places where Mindy does not favor her "sprained" ankle. The most noticeable is when she and Mork are about to open the trunk, she shifts her weight from one foot the other a few times.
Yes Sir, That's My Baby - S1-E19
Continuity mistake: In the scene in bus station, when Mork is talking to the drunk sleeping person, he's holding a bag, there's a shot of the FBI man, and the next shot of Mork, he's not holding the bag anymore.
Visible crew/equipment: In the scene in Mother Bell's right before Lisa and Penny enter, in the close-up of Bickley, Lisa's arm and shadow are visible on the right of the screen.
Revealing mistake: When Mork rollerskates into the wall, the wall moves slightly.
Continuity mistake: When Mindy falls out of the window onto the fire escape, a little bit of her hair comes out of the bun. In the close up, half of her hair is down.
There's a New Mork in Town - S3-E13
Revealing mistake: During the sword fighting scene, the split in the couch is visible before it actually gets split. Also in this scene, when Xerko has Mork at sword point right before Bickley comes in, Mork's ribbon is cut in the close up, but in the long shot, it's intact. Xerko will later cut the ribbon.
