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.
