Super Dave:

       I ran across this on one of the local bulletin boards in Las Vegas.
       Thought you might find it amusing.

                    ~~~~~~~~~~~~~~~~~~~~~~~~~~~

Because you can't see the person who is sending you electronic mail you
are sometimes uncertain whether they are serious or joking.  Recently,
Scott Fahlman at CMU devised a scheme for annotating one's messages to
overcome this problem.  If you turn your head sideways to look at the
three characters :-) they look sort of like a smiling face.  Thus, if
someone sends you a message that says "Have you stopped beating your
wife? :-) " you know they are joking.  If they say "I need to talk to
you :-( ", be prepared for trouble.

Since Scott's original proposal, many further symbols have been proposed:

:-)     humor.
:->     humor variation.       (pointed/sarcastic)
%-}     humor variation.       (warped)
:-(     sad.
:-<     sad variation.         (angry)
%-{     sad variation.         (disappointed)
:_)     tongue in cheek
:-!     foot in mouth
<:-)    for dumb questions.

(:-)    for messages dealing with bicycle helmets.
(8-)    for messages dealing with owls. (or suprise)
d:-)    for messages dealing with baseball.
d :-o   hats off to your great idea
q:-)    for those who wear their caps backwards.
@=      for messages dealing with nuclear war.
o>-<|=  for messages of interest only to women.
~=      a candle, to annotate flaming messages.
