Norman Bates: A boy's best friend is his mother.
Norman Bates: She might have fooled me, but she didn't fool my mother.
Mother: No! I tell you no! I won't have you bringing some young girl in for supper! By candlelight, I suppose, in the cheap, erotic fashion of young men with cheap, erotic minds!
Norman Bates: Mother, please...!
Norman Bates: She just goes a little mad sometimes. We all go a little mad sometimes. Haven't you?
Marion Crane: Yes. Sometimes just one time can be enough.
Norman Bates: Just, don't let them take me back to the institution.
Norman Bates: I don't kill people anymore.
Norman Bates: Conservative clothes never go out of style.
Norman Bates: Oh, I've killed before, and now I'm gonna have to do it again.
Mother: Get that whore out of my house.
Young Norman Bates: She's not a whore, mother.
Mother: I said get rid of her. Or do I have to do it myself?
Young Norman Bates: No, Mother. I'll get rid of her.
Mother: Kill her.
Young Norman Bates: Kill her? I can't! No! No, I can't.
Mother: Alright. Alright. Then I'll do it for you.
Norman Bates: I'm free.
