Once in traveling the Rev. Dr. Bledsoe was exceedingly annoyed by a
pedantic bore who forced himself upon him, and made a great parade of
his shallow learning. The doctor endured it as long as he could, but at
length, looking at the man, said: "My friend, you and I know all that is
to be known." "Why, how is that?" asked the man, much pleased with what
he thought a very complimentary association. "Why," blandly replied the
doctor, "you know everything in this world, except that you are a
fool--and I know that."
