is there a way to use the font to designate sarcasm? like bold or italic or something? or does that take the fun out of using it? i need help with this cause i'm a robot here studying how to blend in with human civilization. and part of the long term plan to beat the aliens and ghosts and such.

In real life I consider myself a coniessuer of sarcasm, but have failed as of yet to perfect my online sarcasm techniques. The rolling eyes emoticon is good... I've also found a great deal of sucess through emphasizing various words as though you're typing the speech pattern of Louis Black:

i.e.
"and so, i went to my health club-- IHOP!!! IHOP is always GREAT, because there's ALWAYS someone there that weighs about 400 POUNDS MORE than you'll EVER weigh!!!"

Man, I had heard that routine a while ago but I never found out who did it. Thanks a lot.

"So I'm sitting there, drinking the BOYSENBERRY..."

Sarcasm translates terribly online, however an obvious font would completely take the fun out of it....its just on of those things i guess.
