This article (http://bit.ly/9DxQoq) is about people who are not good
at something (like humor) but are not aware of it.

In medicine, there is a condition called anosognosia, meaning the
patient is ill but is not aware of it. For instance a person might
have had a stroke, but, because of the location of the stroke, they
don't realize they've had a stroke or that they have weakness,
although it's abundantly clear to everyone else.

The question is: what are you not good at, but don't know it? or, do
you know what you don't know?
