I had this idea when looking through the site's emoticons, and didn't see anything like it. Since I'm no good at making emotes I just used text instead of any sort of facial expression, and have the character alternating between a frown and a smile for some crazy reason.

Obviously if you used this you'd have to be a very demanding person, or else it would so "Please help me" or something.

Please comment if you have anything to suggest!
