Years ago there was a guy who had painted his car bright yellow and put a giant paper-mache lemon on the trunk lid. He also painted "Ocean Dodge Lemon" in big letters on the sides. Every Wednesday he would park on a side street (I lived on the side street) right next door to a Dodge Dealer and sit there all day. He would read, wander about,etc., but he was legally parked and they couldn't touch him. This was before Lemon Laws were enacted. I never did find out what was wrong or if it got resolved...
Remembering that, I was tempted to paint my Ariens riding mower brown with a giant paper mache "dump" on eth back - that was terrible piece of junk...
