- Wouldn't we just love to have him for dinner, Brer Bear? Ain't that just what you been saying?
- Oh, I know, I got it right in the back of my little head. I know what we're gonna do. First thing...
- Go ahead, Brer Bear! Come on! Knock my head clean off!
- Duh... hee... now, see there?
- Yes sir!
- But please, don't fling me in that briar patch!
- Now look here, you keep outta this! Ain't none of your business!
