- Piglet. Where are you going?
- Oh, Piglet. I was only practicing what you told me to say.
- You know, Pooh, you're very convincing. T-hank you, Piglet. But I'm afraid I'm too convincing.
- I can't ask Eeyore to leave.
- Then what are you going to do?
- The only thing I can do, Piglet. Give Eeyore a house warming party.
- I bet old donkey boy will be surprised when he sees the party we're tossing him.
- Sorry to disappoint you, but it's only me, donkey boy.
- I think it's a little late on the surprises, buddy bear.
- So long. Goodbye. We'll miss ya.
