All statements are true in some sense, false in some sense, meaningless in some sense, true and false in some sense, true and meaningless in some sense, false and meaningless in some sense, and true and false and meaningless in some sense.

Probably a bit dry for most, but here are two Nobel-winning economists bantering on for 40 minutes about why economic models are wrong and why you can't make them (more) right.

Near the end there's a quip about how physicists can't build bridges - you need engineers to do that.
