A towel […] is about the most massively useful thing an interstellar hitchhiker can have. Partly it has great practical value - you can […] wrap it round your head to ward off noxious fumes or to avoid the gaze of the Ravenous Bugblatter Beast of Traal (a mindboggingly stupid animal, it assumes that if you can't see it, it can't see you - daft as a bush, but very ravenous).
From yesterday's New York Times:
The White House in December refused to accept the Environmental Protection Agency’s conclusion that greenhouse gases are pollutants that must be controlled, telling agency officials that an e-mail message containing the document would not be opened, senior E.P.A. officials said last week.
The document […] ended up in e-mail limbo, without official status[…]
The Bush Administration's approach to federal regulation (even from tame agencies) that it doesn't want to comply with: If you can't see it, it can't see you.
By the way, it's working.
