Like I said... the mother... Now to understand it the way I understood it, hearing it from the mother... that is, from the mother half of Norman's mind... you have to go back ten years, to the time when Norman murdered his mother and her lover. Now he was already dangerously disturbed, had been ever since his father died. His mother was a clinging, demanding woman, and for years the two of them lived as if there was no one else in the world. Then she met a man... and it seemed to Norman that she 'threw him over' for this man. Now that pushed him over the line and he killed 'em both. Matricide is probably the most unbearable crime of all... most unbearable to the son who commits it. So he had to erase the crime, at least in his own mind. He stole her corpse. A weighted coffin was buried. He hid the body in the fruit cellar. Even treated it to keep it as well as it would keep. And that still wasn't enough. She was there! But she was a corpse. So he began to think and speak for her, give her half his time, so to speak. At times he could be both personalities, carry on conversations. At other times, the mother half took over completely. Now he was never all Norman, but he was often only mother. And because he was so pathologically jealous of her, he assumed that she was jealous of him. Therefore, if he felt a strong attraction to any other woman, the mother side of him would go wild.Dr. Fred Richmond

She might have fooled me, but she didn't fool my mother.Norman Bates
Uh-uh, Mother-m-mother, uh, what is the phrase? She isn't quite herself today.Norman Bates

Sam Loomis: Bob! Run out and get yourself some lunch, will you?
Bob Summerfield: Oh, that's okay, Sam, I brought it with me.
Sam Loomis: Run out and eat it!
Norman Bates: You-... you eat like a bird.
Marion Crane: [Looking around at the stuffed birds while eating] And you'd know, of course.
Norman Bates: No, not really. Anyway, I hear the expression 'eats like a bird' .... it-it's really a fals-fals-fals-fals-fals-ity. Because birds really eat a tremendous lot. But I-I don't really know anything about birds. My hobby is stuffing things. You know .... taxidermy.
Lila Crane: Look, that old woman, whoever she is, she told Arbogast something. I want her to tell us the same thing.
Sam Loomis: Hold it, you can't go up there.
Lila Crane: Why not?
Sam Loomis: Bates.
Lila Crane: Then, let's find him. One of us can keep him occupied while the other gets to the old woman.
Sam Loomis: You'll never be able to hold him still even if he doesn't want to be held. And, I don't like you going into that house alone.
Lila Crane: I can handle a sick old woman!
California Charlie, used car salesman: I'm in no mood for trouble.
Marion Crane: What?

Marion Crane: Can I trade my car in and take another?
California Charlie, used car salesman: Do anything you've a mind to. Bein' a woman, you will. That yours?
Marion Crane: Yes, it's just that - there's nothing wrong with it. I just...
California Charlie, used car salesman: Sick of the sight of it! Well, why don't you have a look around here and see if there's somethin' that strikes your eyes and meanwhile I'll have my mechanic give yours the once over. You want some coffee? I was just about...
Marion Crane: No, thank you. I'm in a hurry. I just want to make a change, and...
California Charlie, used car salesman: One thing people never oughtta be when they're buyin' used cars and that's in a hurry. But like I said, it's too nice a day to argue. I'll uh - shoot your car in the garage here.
