(someone knocks at the door)Samantha: Ahm … that's Gladys Kravitz.
Merle: Hey, can you see through walls? I can't seem to get the hang of it.
Samantha: (laughs) No magic involved, Merle. I just know from the knock and the timing. (opens the door, Gladys is there, just as she said) Oh, hi, Mrs. Kravitz. What a surprise.
Mrs. Brocken: He's got a lot of studying to do.
Samantha: Oh, what are you working on now, Merle?
Merle: Elementary spells and incantations.
Mrs. Brocken: Now, you're not to help him, Samantha.
Samantha: Don't you worry, I won't.
(Glady and Abner observe the Stephens house)Gladys: How about that? Kind of funny, people like that going into the Stephens house.
Abner: They look normal to me.
Gladys: That's what's funny about it.
