Remember the banana duct-taped to a wall and labeled “art” that sold for $120,000? On Saturday, a New York man walked up to the art installation and ate the banana.

Clearly some people have more money than sense. Why anyone would pay 120g for a banana an strip of duct tape that cost less than a buck stuck to the wall is beyond me. Any 5 year old could produce that "Art" if you gave them a stool to stand on to get it that high up the wall.

Sure your paying for the "Certificate of Authenticity". It certifies the holder as an authentic moron.
