- You'll stay out of this, please? Thank you very much.

- Now, if you'll come here, Dr. Norton. I'd like to ask you a few questions about your life.

- Now, tell me, what school did you attend?

- P.S. 31, Oyster Bay.

- No, I mean what medical school?

- Oxford.

- Oh, in England.

- Is that where it is?

- You mean you went to school at Oxford, and you don't know it's in England?

- Well, tell you the truth, it's so foggy over there, I don't know where it was!

- Doctor, just exactly where do you practice medicine?

- Oh, I don't have to practice it, I know it.

- Dr. Norton, you know what I think? I think that you're no doctor. You're a phony!

- Mr. Kramden, this whole thing is a hoax!

- It's bad enough for you to come here, and try to dupe this magazine with your phony story.

- But to give false hope to poor Mr. Kramden here, who has only six months to live is unforgivable.
