Darrin Stephens: Sam, don't expect your mother to be gracious. She doesn't do imitations.
Samantha: Now when it comes to Santa Claus, most mortals don't believe he exists... just like they don't believe in witches.
Samantha: Gladys, what are you doing?
Gladys Kravitz: I came over for a snoop, uh, a scoop of sugar. I hope I'm not disturbing you.
Samantha: I'm not a bad witch! I'm a good witch.
Darrin Stephens: Her mother's a bad witch.
Samantha: Then I thought of the most brilliant scientific mind of the age.
Dr. Bombay: Thank you.
Samantha: But he died a year ago, so I decided to call you.
Samantha: Try to control your temper. Remember, "Peace on earth, goodwill to men" includes witches.
Samantha: Darling, I've been trying for weeks to give this house a thorough cleaning. These carpets are filthy.
Darrin Stephens: How can you worry about dirt on the rugs when we're about to see the surface of the moon?
Samantha: The moon could use a vacuuming too. All that dust... yych.
Endora: Samantha, I will not stand here and be insulted by something which is 94 percent water.
Darrin Stephens: Oh, yeah! Well, what about something which is a hundred percent hot air?
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.
