Know-It-All Neighbor

Chaffee could talk on any subject whether he knew anything about it or not. Mostly he didn't. One day his neighbor Nibley could stand no more.

- Do you realize - asked Nibley - that you and I know all there is to be known?

- Do you really think so? - said Chaffee.

- How do you figure that?

- Easy - answered Nibley.

- You know everything except that you're a damn idiot. And I know that!
