Witches live for so long that they have to have several wills to help them thin out all of the things that they have accumulated.
Sabrina (to Hilda and Zelda): We're going to the Aquarium. We'll be back by 6. I'm driving! Oh, no I'm not... I don't have a car...
Harvey: We're going to Big John's. If you order the Lumberjack Special before 8:30, you get to keep the plate.
Valerie: If you get there before 8:15, you get to keep the fork.
Harvey: Do you think Big John's going out of business?
Zelda: May I please be excused?
Great-Grandma: Not until you've thought about what I've said. (to Hilda and Sabrina) I just wish I could remember what it was...
Boyd: We got pudding at home. It may be canned, it may be government surplus, I don't know, it may even be pie fillin' but it's ours.
Great Grandma: Oh Racine, I know you're unhappy but it was fair. Now Hilda and Zelda got the magic book and you got what you chose: all my money.
Sabrina: They got all of great grandma's money?
Hilda: Yep, and they bought a mansion and a jet, and several butlers.
Zelda: Don't forget tiaras for Maw Maw.
Hilda: And then all the money was gone.
Racine: We didn't just spend it, we invested some of it.
Boyd: Yeah, who knew chihuahua racing wouldn't take off?
Hilda: Ah... everyone?
Racine: Lord have mercy, look at the number of towels.
Boyd: It's like there's one towel for each person.
The title is obviously a punny play on the term "white trash".
