"Known and Unknown"

Thus reads the title of Donald Rumsfeld's book, apparently taken from a remark that he made back in 2002 when he was the Secretary of Superciliousness, WMD's were all the craze, and the Iraqi-invasion die had been cast:  

"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." 

It's little wonder the White Wabbit of Wherazona was recently heard to quip, "Whasup with that Wumsfeld? Thank god you was wewieved of you dwuties."
