Sarcasm is logic with a funny bone.
Sadly, some people have their funny bone violently sucked out moments before birth. Or, if not at birth, at some point in his or her life.
I should start a charitable organization aimed at eradicating the scourge of Sarcasm Cognizance Disorder from the planet.
If only we could discover the gene.
Oh. LOL. Sorry I could not tell.
