Here in Washington, several years ago a man tried to have a baseball field constructed on his property, which he wanted the neighborhood kids to be able to use, and for family functions. He was told "hell no" by the zoning crowd. In revenge, he discovered they didn't have the power to prevent him from painting his house yellow with bright polka-dots, so he did just that.
Hmm... all I could find were these letters to the Seattle Times, and no mention of the polka dot house I remember hearing about, but still the baseball field story is neat:
