To most people, putting a budgie cage on your head and jumping into the ocean with a live tiger shark is an obviously stupid thing to do.
But you try telling Australian Shaun Harrington that.
Harrington, 27, jumped into the water off Coolangatta on the Gold Coast last weekend, armed with only a flimsy bird cage, to be filmed with a tiger shark that had been hooked on a line by a professional fisherman friend.
The "cage diving" stunt, to promote his and twin brother Dean's clothing line, was uploaded on YouTube this week.
The 33-second clip shows Harrington, the daredevil, putting the cage over his head before asking a friend: "I'll be alright, eh?"
"Yeah mate, no worries, they don't have real big teeth," the friend replies.
Then 2.5-metre predator lunges, narrowly missing him and slamming into the boat.
The close call prompts a screaming and cursing Harrington to leap back into the boat while using the $50 cage to fend off the shark.
Harrington said he would not be repeating the stunt.
"I was pretty much walking on water to get back into the boat," he said.
"Mate, there's no way in hell I'd ever jump back in there again with it.
"It's just not f****ing worth it, they're just too unpredictable. They're crazy creatures."
But Harrington, an avid surfer, said the incident would not stop him from returning to the waves.
"There's too many other people that can get eaten," he joked.
Unsurprisingly, James Cook University shark expert Colin Simpfendorfer was not impressed by the video.
"I just shook my head and thought it wasn't very smart," he said.
"It takes a split second for it to go very bad."
