*Sarcasm*. </sarcasm>. #Not! Since the dawn of the postmodern age, ironical writers have struggled to imbue the printed word with the nuances of sarcasm. Solutions involve signposting suffixes like "Joke!", so as to spell out any intended irony to those readers too thick to work it out by themselves. (Joke!) Only last year, G2 reported the invention of the "SarkMark", a piece of punctuation that has solved this massive problem once and for all. ;)
In fact, it was such a great idea (not!) that another typographer has come up with perhaps the best solution yet: the "Sarcastic Font", a typeface that renders sarcastic comments in reverse italic script.
