Quote context

[...]

- Now this person that you call Harvey, now who is he?

- He's a rabbit.

- Yes, perhaps.

- But, uh, just who is he? Someone your brother picked up in one of these bars?

- Doctor, I've been telling you, Harvey is a rabbit. A big white rabbit six feet high. Or is it six-feet-three-and-a-half? Heaven knows, I ought to know. He's been around the house long enough.

- Mrs. Simmons, if I'm not mistaken...

- Doctor, don't you understand? The rabbit's name is Harvey. Harvey lives at our house.

- Elwood buys theater tickets and railroad tickets for both of them.

- He's lost interest in everything else.

- And here I am trying to get Myrtle Mae started with a nice group of young people. That's my daughter.

- Doctor, I'm going to tell you something I've never told anyone in this world before. Not even Myrtle Mae.

- Every once in a while, I see this big white rabbit myself! Now isn't that terrible? And what's more, he's every bit as big as Elwood says he is!

- Now don't ever tell that to anybody, Doctor. I'm ashamed of it.
