Continuity mistake: When Larry tells Darrin that he is going home, the blinds behind Darrin are shut, however in the close up of Darrin, the blinds are open.

I, Darrin, Take This Witch, Samantha - S1-E1
Audio problem: When Samantha and Darrin are at his ex-girlfriend's house for dinner, Samantha is doing all kinds of things to sabotage the dinner, even making a gust of wind come through the front door thus blowing the ex's wig off. The ex girlfriend is screaming but the screams don't match up to what her mouth is doing.
Continuity mistake: In the opening scene, Bertha (Later Aunt Hagatha) puts her cookie on her plate next to her cup. In the next shot it disappears.
A Nice Little Dinner Party - S1-E19
Continuity mistake: The train shown is pulled by four diesel locomotives, "A" unit leads with two "B" units sandwiched between a second "A" unit. When Mrs. Stevens pulls the emergency stop cord, which would not likely be on a long distance passenger train, the locomotive shown doing an emergency stop is a steam one. Not to mention that by the time of this episode steam engines were obsolete, and less likely to have been employed, especially in passenger service.
And Something Makes Three - S1-E12
Other mistake: While Gladys Kravitz is standing in front of her house, which is across the street from the front of the Stephens' house, Gladys sees the Stephens' backyard just as Sam zaps a swimming pool and then zaps it away, but since the Stevens' backyard is located behind the house where the living room and dining room are, this would be impossible even for nosy Gladys Kravitz.

There's No Witch Like an Old Witch - S1-E27
Visible crew/equipment: As Samantha helps Aunt Clara out of the closet, as Samantha says, "Don't go 'way!" the boom mike's shadow becomes momentarily visible at the top of the screen. (00:02:00)
Continuity mistake: The shaving cream smears on the mirror are different in the close-ups than they are on the wider shots. (00:04:25)
Character mistake: When Darrin is on the deck of the yacht, he says something about the salt air.

The only body of water to support a yacht 3 miles off shore is Lake Michigan which is fresh water.

Visible crew/equipment: When Abner comes over to the Stephens' near the end to say Gladys' problem has got worse, just as the door is closing a crew member's hand can be seen near the Bob ensuring it closes. This is just before the shot goes to Darrin.

Visible crew/equipment: When Aunt Clara's satchel and umbrella are "floating" up the stairs the shadow of the boom pole making the magic is visible above the Menorah at the top of the wall.
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.
