Tim: Hi, Mark.
Mark: Hey.
Tim: Having an apple?
Mark: Yeah.
Tim: I like apples when they're peeled, but to peel one, what would you need? You'd need a knife, wouldn't you? Hmm, boy. Oh, wait a minute, I got one. I'll just peel that for you. Use this knife here.
Mark: Oh, maybe I'll have a banana.
Tim: Or maybe you'll sit down.
