- Oh, Yogi, you're not going downstairs?
- Stay put. I'll pick up a snack and we'll tippy-toe out the back.
- One of these and two of those. Three of these and four tomatoes. Five of these and ye-he-hey.
- Oh, no, you don't. I need a partner.
- Stranger, you sure can shake a mean leg.
- But aren't you warm in that fur coat?
- Well, I can't take it off. I'm a bear.
- Bear! Help, a bear! Run for your lives! It's a bear! Call the sheriff! Help! Get my gun!
- Gosh, if it wasn't for you, we never would've gotten away.
