A passenger on a train visited the dining car and ordered a bowl
of soup.

When delivered, it had a fly in it and the outraged passenger
wrote to the president of the railroad, expressing his dismay and
vowing never to ride that railroad again.  Then he received a
letter from the president, apologizing profusely, vowing that
this was an unprecedented occurrence and explaining the steps
that had been taken to insure it never happened again.

The passenger was almost persuaded until he discovered that the
envelope also contained a small slip of paper containing his name
and address and the handwritten notation:

"Send this jerk the bug letter."
