Quote context

[...]

- Oh, my. Gopher has a grandfather. Why, one gopher is bad enough. Two would be nothing short of disaster.

- I have to warn the others immediately.

- We must do something to stop Gopher's grandfather from destroying our very way of life, not to mention my rutabaga-potato.

- Any questions?

- Oh, perhaps we should have a party to welcome Grandfather Gopher.

- Oh, that's a very nice idea, Pooh Bear.

- It's twice as nice as nice. It's incredibibble. It's unbelievabibble. Why, it's downright unnecessary.

- Don't you understand? If a son takes after his father and fathers after their fathers, it goes without saying that Gopher must take after his father who takes after his father!

- We must keep Gopher's grandfather so busy he won't have time to destroy anything.

- Pooh Bear, you shall be in charge of keeping him busy doing nothing.

- Yeah, Pooh boy. Nobody does nothing like you do nothing, and that's saying something.

- Why, thank you. It's nice to know I'm good at something, even if it is nothing.
