MIRANDA: Doctor, is the squirrel going to live?
DOCTOR: There’s been massive trauma. We could of course try to save him but it would be costly, difficult and we’d have to send away for some special really tiny instruments.
GEORGE: Well, uh, are there any other options?
DOCTOR: We could put him to sleep.
GEORGE: What might that cost?
DOCTOR: Well, it’s by the pound. So ... about 80 cents.
I came here just to see if someone posted that. LOL.
