A post-Katrina folk art has developed in New Orleans: Dead Fridge Grafitti.
For those who don't know, refrigerators left with no power full of rotting food for 6 weeks are generally unsalvagable, so there are thousands on New Orleans area curbs. Some returnees tried opening theirs; survivors generally reccomend against it. Best practice says to duct tape the things shut & cart 'em out unopened.
People started writting on them, starting with the basic "TRASH", "TOXIC", or "DO NOT OPEN".
Then they started getting more clever: "SIR STINKS ALOT", "FREE TO A GOOD HOME", "KATRINA, YOU BITCH!"
My favorite so far read "WAS COLD HEARTED, NOW TOTALLY CORRUPT".
Edit:
Ah, this important trend is being widely recognized:
