This one is by way of apology to a man who at first seemed befuddled, unfocussed and seriously out of his depth, but who--whadya know?--turned out to have a spine (such a rarity in the White House that it deserves to be acknowledged--and applauded):
A Defense Secretary named Chuck
Manifested a great deal of pluck.
Said Obama to Chuck,
"Man, your pluck sucks!"
And now poor Chuck's plum out of luck.
