Is it possible to have a sarcastic face emoticon

[DillyDally]

Not sure what it would look like but something to add to posts to indicate I don't really mean it honest guv'nor..
It might help me not to offend / alienate as many people as I currently do.

Wouldn't a wink work?

We also think the wink's supposed to do this but if you find one you like and email it to [email protected] we'll certainly consider it.
