As American's we're very eager to stop things. We're so eager to stop things, in fact, that we feel compelled to write about it on stop signs. Never mind that it's a misdemeanor and could result in a fine, or worse case scenario cause an accident, stop signs exist and therefore they must be defaced.
While not condoning such behavior, I certainly enjoy photographing it. I came across this anti-war message recently in Chicago's Lakeview neighborhood:

And on a less serious topic, here's one that I stumbled across in 2008:

Note: I reprocessed that second photo to bring it up to 2013 standards. That file was only uploaded at 800px and had tons of chromatic aberration-- something I just didn't pay as much attention to back then.
