Native Wit
JOHN was thought to be very stupid. He was sent to a mill one day, and
the miller said, John, some people say you are a fool! Now, tell me
what you do know, and what you don't know.--Well, replied John, I
know millers' hogs are fat!--Yes, that's well, John! Now, what don't
you know?--I don't know whose corn fats 'em!
