Billy Rubin is just the gruff expat Australian that everybody *thinks* lives in my house. I actually created the sign after a bad spate of dogs—or more specifically their human thralls—leaving "presents" all over my yard. Dog walkers responded postively, which is too bad because my throwing arm could use a workout.The same sign more recently served me during the Occupy Portland March on 10/6/11. I think the message works on that level, too.
No bad words, thanks!
