Read this article from a Cornell anthropologist that details how sarcasm may have been a survival trait over the years. Her example seems a little far fetched, but the notion that social interaction would be a selectable trait in our long history of development makes total sense.

The next time someone says that you’re too sarcastic, just grin to yourself and imagine them eaten by a lion.
