Aunt Petunia
- Aunt Marge: [to Vernon] You mustn't blame yourself about how this one turned out, Vernon. It's all to do with blood. Bad blood will out.
- [to Petunia]
- Aunt Marge: What is it the boy's father did, Petunia?
- Aunt Petunia: Oh, nothing. He didn't work; he was unemployed.
- Aunt Marge: And a drunk too, no doubt?
- Harry: That's a lie!
- Aunt Marge: What did you say?
- Harry: [a little enraged] My dad wasn't a drunk!
- [Aunt Marge accidentally breaks the glass she it holding, which shatters into pieces, startling everyone else]
- Aunt Marge: Oh, don't worry. Don't fuss, Petunia. I have a very firm grip. Boy, clean this up.
- Uncle Vernon: I think it's time you went to bed.
- Aunt Marge: Actually, it has nothing to do with the father, it has to do with the mother. You see it all the time with dogs. If there's something wrong with the bitch, then there's something wrong with the pup.
- Harry: [completely loses it] SHUT UP! SHUT UP!
