Unknown Unknowns

United States Secretary of Defense Donald Rumsfeld won the 2003 Foot In Mouth Award for this comment:

'Reports that say that something hasn't happened are always interesting to me, because as we know, there are known knowns; there are things we know we know. We also know there are known unknowns; that is to say we know there are some things we do not know. But there are also unknown unknowns — the ones we don't know we don't know.'

I wish I was his speech writer.
