Barney: The world is flat.
Christopher: No. It isn't.
Barney: Sure it is. Look out at the horizon. It's flat, flat, flat for as far as you can see.
Christopher: You lie.
Barney: Do you know anyone who has proved the world isn't flat.
Christopher: You are so deluded, it is sad.
Barney: Everyone I know thinks the same, that the world is all flat
Christopher: You're all wrong. You're just too stoopid to know it.
Barney: So, if it isn't flat, what shape is it?
Christopher: How can you be so dense? Don't you have a picture of the world?
Barney: Yeah, it's printed on a piece of paper, and it's flat.
