Quote context

[...]

- While I've had many patients out here with animals, I've never before had a patient with an animal that large.

- Yes, Doctor. She called him Harvey.

- Unusual name for an animal of any kind.

- I want her to have a hypo at 6:00, with another one at 9:00.

- Willie...

- Yes, yes, but I'm coming.

- My formula 9-7-7.

- Hiya, Dr. Chumley. How's every little...?

- Hey, what's with you and that hat?

- Hat?

- Here's your hat, Dr. Chumley. I'm wearing my hat.

- This isn't my hat. Must be yours, Doctor.

- No, Doctor, mine is... Mine is...

- Harvey?

- Yes. Yes, Harvey.
