I love Sarcasm. No, Really I do.

The New York Times has an article on the neurology of sarcasm.

To her surprise, though, the magnetic resonance scans revealed that the part of the brain lost among those who failed to perceive sarcasm was not in the left hemisphere of the brain, which specializes in language and social interactions, but in a part of the right hemisphere previously identified as important only to detecting contextual background changes in visual tests.

It's really cool to know that detecting a change in intent is similar to recognizing foreground/background differences visually. It makes me wonder if highly emotionally and socially intuitive people have a skill that's similar to staring at those odd pictures that turn 3D if you see them right.
