Someone might hunt up some more background on this.  I was a bit 
surprised that the brain seems to have a specific region that deals 
with sarcasm.  Personally I don't think I use sarcasm very often and 
(especially in an all text channel) don't always pick up on it.

Thanks to the person who pointed this article out to me.
