- Why, Piglet, you weren't the bother. I was. Me and my habit of losing things. Isn't that so?

- Yep, buddy bear's the one.

- Yes, thank you... I think.

- So, you see, I've learned my lesson. I'm never going to lose anything again, provided I can find it.

- Wait a minute! Enough of this lost and foundies.

- Did you say you were singing, Piglet?

- Yes.

- Ah! I never knew you could.

- Well, actually...

- Why didn't you ever tell us?

- Yeah, yeah! Go ahead and hum a few bars.

- Oh, now, I don't really sing all that wonderfully. I'm just a beginner, you know.

- Nonsense, Piglet! We'd love to hear you.

- And now, my very dear friend, Piglet, who was misplaced by me, but has since been found and will stay found, will sing for us.

- La-la-la-la-la-la-la-la...

- You built a wonderful stage, Pooh Bear. I assume you found my hammer to nail it together?

- Well, Rabbit, I didn't actually find the hammer. So I never actually hammered the nails in. But don't tell anyone.
