The World's Online Marketplace - A site that has become so famous it needs no description. Instead here's a list of some amusing items that have been listed for sale on ebay: New Zealand, an Air Guitar (bought for $5.50) , a single cornflake (�1.20), water from a cup Elvis (possibly) drunk from ($455), the secret to invisibility (4 available!) and a Cryogenically Frozen Pet Fish ( at the time of writing worth $0.55).

Well they do say you can sell anything on the net...but an air guitar!
