This Monday the first sign I noticed coming up the escalator was:
"Turn swords into plowshares"
Which immediately made me think: what the heck is a plowshare. Which led me to:
In agriculture, a plowshare (or ploughshare) is a component of a plow (plough). It is the cutting or leading edge of a moldboard which closely follows the coulter (one or more ground-breaking spikes) when plowing.
The plowshare itself is often a hardened blade dressed into an integral mouldboard (by the blacksmith) so making a unified combination of plowshare and moldboard, the whole being responsible for entering the cleft in the earth (made by the coulter's first cutting-through) and turning the earth over.
Okay, so our protester of the week Comrade Birkenstocks is obviously a fan of Michael Jackson's 1991 single Heal the World or maybe just a fan of the book of Isaiah.
Either way, I took his sign to mean that we should take our swords and fashion them so as to be able to attach them to plows and become farmers instead of warriors.

or since there aren't too many weapons systems in use inside the Pentagon proper:
