Season 9, Episode 6: "The Merv Griffin Show"

Doctor, is the squirrel going to live?

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.

Well, are there any other options?

We could put him to sleep.

What might that cost?

Well, it's by the pound, so about 80 cents.
