I still don't know how to make a blue clicky. I found this and some other poems by Rumsfeld. You'll have to find them by searching Google.

                   The Unknown

                   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.
