Two Australian pranksters' idea for a stunt nearly went horribly wrong off the Gold Coast. The plan was to go "cage diving" with sharks, but not with a professional shark-proof cage.

Shaun Harrington instead was using a cheap bird cage that he planned to put on his head as part of a website marketing ploy.

He then came dangerously close to an eight-foot tiger shark that had been caught by a fisherman on the boat. The shark lunged at him, but missed and Harrington quickly scrambled back aboard.
