I always get a kick out of self-contradicting signage, especially when it's "official." There's a photo in this article [[you may have to click it to enlarge) of a sign in the Capitol that says "NO SIGNS in the CAPITOL." LOL!

ACLU calls Capitol's rule forbidding signs unlawful

Okay. technically it's not quite inside the Capitol. It still looks funny. It's interesting that the article refers to these signs as "notices." The author must have appreciated the hypocrisy.

Now I want a "PROHIBITIONS PROHIBITED" sign.
