Marriage, Witches' Style - S5-E21
Revealing mistake: The wires holding the cake knife are visible as it's cutting a slice. (00:00:25)
Marriage, Witches' Style - S5-E21
Revealing mistake: In addition to Samantha, Elizabeth Montgomery also played Serena. In scenes where both characters appeared, Elizabeth would face the camera and play one character and another actress, Melody McCord, would play the other with her back to the camera. But in this scene, when Mr. Beams tells Serena she has a luncheon date with her intended at the rotisserie, Melody (portraying Samantha), with her back to the camera, inadvertently turns her head, revealing her face. (00:07:20)
Marriage, Witches' Style - S5-E21
Revealing mistake: At the end of the episode, during Serena and Samantha's second meeting with Mr. Beams, in the wideshots of the two women sitting on the couch and also when they're both poking their heads through the doorway, Serena's body double actually appears face-forward. Additionally, in the closeups of Serena and Sam on the couch, both are played by Elizabeth Montgomery, and we can see the wall's color difference behind them due to the use of the split-screen technique. (00:22:25)
Samantha's Yoo-Hoo Maid - S6-E2
Revealing mistake: Whenever Esmeralda sneezes and makes the furniture in the living room levitate you can see the wires.
To Trick or Treat or Not to Trick or Treat - S6-E7
Revealing mistake: The wire used to control the flaming arrow's flight is visible in the closeup. (00:21:00)
Revealing mistake: Paul Lynde is supposedly "in" the mirror near the front door, but as he waves his arm to cast a spell, the shadow of his arm waving is visible at the far left, revealing he is actually standing off camera at a spot where his reflection is visible. Elizabeth Montgomery also briefly glances at him. (00:02:25)
Serena Stops the Show - S6-E22
Revealing mistake: The face of the double can be seen when Samantha and Serena come from the kitchen. (01:10:00)
Revealing mistake: After Samantha restores The Leprechaun's power he walks into the backyard, and when Endora, who's on the roof, uses her powers to have him float up to join her, the wire cables can be seen giving him the needed boost upwards. Later, the cables can be seen again when Sam lifts him up in the living room. (00:09:40)
Revealing mistake: When Sam and Endora are sitting on the wing of the airplane, you can see folds in the blue backdrop for the sky.
Revealing mistake: The wires helping the Good Fairy fly are visible as she flies around the living room. They also are visible when Samantha flies outside a couple of minutes later. (00:11:50)
Samantha and the Troll - S7-E19
Revealing mistake: The wires used to help Adam's cup of milk float around are plainly visible. (00:00:25)
Samantha is Earthbound - S8-E16
Revealing mistake: When Samantha, Darrin and Dr. Bombay are in the living room and walk as a group towards the television, you can see the crease in the carpet where the floor is going to collapse.
Samantha is Earthbound - S8-E16
Revealing mistake: When Samantha is in the tree at the party, you can see the reflection of the branch against the "sky" revealing blue painted sky.
Revealing mistake: Darrin casts a shadow revealing painted sky background when he goes out to pay cab. Later, when he goes out to get in helicopter the neighborhood is not the neighborhood we normally see outside the Stevens' house. There's an Amoco gas station across the street.
George Washington Zapped Here (2) - S8-E22
Revealing mistake: When Samantha is showing Martha the washing machine, look at Martha's shadow; it's visible on the "trees" outside the window in the door, making it obvious it is a painted backdrop. (00:05:35)
Samantha's Witchcraft Blows a Fuse - S8-E25
Revealing mistake: When Darrin brings the ladder around to the front of the house, it's obvious this is not the actual house but a stage set; the background is obviously a painting and the driveway/garage have disappeared. Further the outside and windows are too narrow to be the actual house. The den is larger than the small facade in the scene.
Samantha's Witchcraft Blows a Fuse - S8-E25
Revealing mistake: When the officers pull away, the shadow of the car is visible on the painted backdrop of trees. This isn't the neighborhood of Morning Glory Circle with the Kravitz House across the street. The shadow reveals it's a stage backdrop. Further, this is basically the same as Allergic to the Macedonian DoDo Bird from Season 3, with the same DoDo Bird costume.
Answer: Larry had been telling Darrin what it means psychologically that Samantha gave the coat away. Larry said giving it away meant she's happy being married but if she liked the coat it means she desires to be single and carefree. So when Darrin sees the coat, he immediately thinks Samantha doesn't want to be married and the fact that she twitched it means (in his mind) she wants to be a single, carefree witch again.
