Quote context

[...]

- Anyhow, why worry? Maybe I drew a lucky number.

- You didn't take any number from that box.

- I had the exact number of disks in it, one for every man and woman, except the six people I named.

- If you had taken a number, we would have been one short.

- The drawing is over. You can't open a new one or issue new numbers without starting a revolution among the lucky winners.

- It's about time I donated something to this setup.

- I won't be needed. I never have been.

- Anyhow, I didn't give up much by not drawing. What's one chance in 600?

- Leaving me will save fuel. Let it stay that way.

- And, Doctor, I hope you won't say anything to Joyce.
