Fact: Some people don't get sarcasm.

' “A lot of the social cognition we take for granted and learn through childhood, the ability to appreciate that someone else is being ironic or sarcastic or angry — the so-called theory of mind that allows us to get inside someone else’s head — is characteristically lost very early in the course of frontotemporal dementia,” said Dr. Bradley F. Boeve, a behavioral neurologist at the Mayo Clinic in Rochester, Minn.' - The New York Times

Relatively interesting article about sarcasm and the fact that there exist some, other than those who just simply have a bad sense of humour, who just don't get sarcasm. I mean, actually.
