- Never fear, long ears. I'm just the tigger to invent that some kind of something for you.

- The only thing you can invent is excuses for not working.

- Huh. The accepting of challenges is one of the things us tiggers do the best.

- Why, I'll invent something the likes of which nobody's ever seen, or my name isn't Tigger.

- I'm very worried, Pooh. Tigger hasn't been out of his house for seven whole days now.

- Actually, Piglet, I believe it has been closer to a week.

- I wonder what he's doing in there.

- He's inventing in there, that's what.

- And keep your voices down. You're derailing my train of though.

- I'm certain, if we ask very politely, Tigger will come out.
