Revealing mistake: When looking out of the Steven's kitchen window, the view outside changes completely during different episodes of the show.
Revealing mistake: The hallway that leads to the den and the back door of the kitchen has a door at the end of it, when this door is opened we see what looks like pine trees and mountains, we know that the Stevens have neighbors on that side of the house, so that when the door is opened you can blatantly tell that it is a picture.
Revealing mistake: In several episodes, the window over the kitchen sink is shown from the outside, while snoopy people look in. The window shown in these exterior shots is far too low to be the same window that is over the Steven's kitchen sink, which is shown in many shots looking out.
Revealing mistake: The series is supposed to take place in Westport, CT. Westport, CT doesn't have palm trees or the California mountains. Several shots outside of the house reveal the mountains and palm trees are when driving in several episodes.

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.
