1. Maurizio Cattelan's 'America' (2016) is a fully functional toilet, fashioned from solid gold. It is made out of 223 pounds of gold, (modeled after a standard Kohler toilet) a weight valued at about $10 million in current gold markets. Sotheby's is betting it can auction off the golden bowl for even more. Does this seem ridiculous to you, especially knowing someone will buy it?
