Darrin Stephens: Sam, don't expect your mother to be gracious. She doesn't do imitations.
Samantha Fights City Hall - S5-E9
Trivia: Because Erin Murphy, who played Tabitha, was ill, her fraternal twin sister Diane took her place in this episode. By this time, Erin and Diane didn't resemble each other as much as they once did, and it was obvious to regular viewers of the show that it wasn't the Tabitha they were used to seeing. The producers received several letters asking "Who was that?"

Question: Darren was angry at Samantha for getting rid of his favorite coat so, why was he even angrier when he got it back?
Answer: I haven't seen the episode, but generally in the show, Darrin was always suspicious that Samantha always used some kind of witchcraft for any situation (even if she didn't). He probably figured the same thing with the coat while in her possession.
You should watch the episodes in question before giving an answer so you know what you're talking about.
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.
