- Hi, everybody! Seen any fun laying around waiting to happen?
- In case you haven't noticed, we happen to be working.
- Work? Ha. Why, I don't even know the meaning of the word.
- I really must say this work is a great deal of... work.
- Ah. It's true. If only there were some kind of something to help us clear this snow.
- Hmm. Sounds like an idea whose time has passed.
- 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.
