"the first in American history guilty of being p.w.b., president while black"

Stanley Fish's column in The New York Times on the Gates scandal ends like this:

Gates and Obama are not only friends; they are in the same position, suspected of occupying a majestic residence under false pretenses. And Obama is a double offender. Not only is he guilty of being Housed While Black; he is the first in American history guilty of being P.W.B., President While Black.

But you really need to read it all.
