Continuity mistake: In "The Unsinkable Mr. French" (season 5), the amount of whipped cream on Mr. French's jacket increases as he's getting up from the couch. (00:23:00)
Other mistake: Season 5 sees the family celebrating and reminiscing when the children came to live with Uncle Bill. Buffy and Jody were 6 when they came to live with Uncle Bill. This would make the twins now 11. In a later season 5 episode, Jody is trying to get a female classmate to like him in order to secure a stamp he wants for his collection, the Spanish triangle. His antics catch the concerned eye of his Uncle Bill who asks a few times during the episode, "is it normal for a 9 year old boy to be interested in girls?"
Revealing mistake: When Cissy is at the piano as Buffy sings and dances for Uncle Bill, only her arms move up and down instead of across the keys, indicating that's it's an off-camera person actually playing the tune. (00:16:30)
Revealing mistake: Obvious studio setting with the fake overlapping grass in the park while Cissy and the boyfriend talk. (00:18:30)
Suggested correction: In which episode does this occur?
Visible crew/equipment: Shadows from the boom can be seen in the corners and upper walls in the foyer and living room when French is conversing with Uncle bill.
Suggested correction: Which episode?
Arthur, the Invisible Bear - S2-E4
Audio problem: When the station wagon pulls into the mountain clearing there is no movement with the trees indicating they are on a sound studio, as some of the dialogue is acoustic. (00:24:00 - 00:24:30)
The Day Nothing Happened - S2-E20
Revealing mistake: The snowman is an obvious Styrofoam props the kids have set up in the family room, as the fake snowflakes fly right off it during the kids play, including the white patches beneath the body.
Continuity mistake: After Cissy and Danny leave for the concert, when Sharon follows the twins into the kitchen she's wearing tan pointed toe pumps, but in the next shot Sharon places her purse on the kitchen counter then heads toward the table, and now she's wearing very different shoes (the actress is wearing some type of fringe moccasins). (00:09:15)
Other mistake: When Cissy 'dials' Sharon's number to ask her about babysitting the kids, Sharon is shown already crossing her living room to the phone as it rings.
Visible crew/equipment: Oliver (a dog) jumps up on Uncle Bill's bed and starts barking at him. The real reason the dog is barking: in the shots of Oliver, the shadow of a towel or some sort of toy can be seen being waved around in order to agitate the animal. It even briefly pops into the shot a couple of times. (00:10:45)
Other mistake: Jane Webb is listed in the closing credits as "Store Lady". She actually played the "Story Lady". (00:25:00)
Family in Paradise: Part 1 - S4-E25
Character mistake: The hunky male tour guide compliments Cissy on her brown hair when she's an obvious redhead.
Visible crew/equipment: Shadow of the boom swings when Cissy, Kathy, and the kids enter the bedroom.
