I noticed a sign stuck in some dirt next to a 3-way intersection today. It roused my curiousity mainly because it did something that I have seen for the very first time.

It appended dollar-signs next to a message exhorting the reader to "Promote the Constitution."

Make money by promoting the Constitution? This can only be a neoconservative nocturnal emmission. 

Here is a close-up of the sign.
