I don't remember the exact details. Supposedly Banksy wanted to the destroy the piece, but the shredder gave out and stopped half way through. So it was definitely planned in some way or form. Probably made the painting more valuable, too.

Another favorite of mine was when somebody duct-taped a banana to a museum wall, or whatever it was, and called it art. Expensive, too. Then someone ate the banana and put the peel up.
