"If I'm not untangled in exactly four seconds, it's about to get all Amity Island up in this b***h."
The two men eventually wrestled the beast to shore with ropes, and when it refused to die, they took it to the nearby Coogee Aquarium. After a week in captivity, the shark, determined to maintain its newfound celebrity status, proceeded to vomit up a human arm in front of a crowd of terrified onlookers, officially making this the coolest thing anyone has ever paid to watch happen prior to the invention of TV. What's more, the arm in question still had a length of rope tied to the wrist, and an autopsy determined that the arm had been removed from its body with a knife. After putting the shark through a series of rudimentary knife-fighting tests, it was determined that somebody else had cut the arm off, and the shark had merely swallowed it and spit it at some people who looked like they weren't scared enough of sharks.
"This guy wasn't even worth digesting."
This is where the story would end if it hadn't been for a rare tattoo on the arm that allowed investigators to identify it as belonging to Jim Smith, a former boxer who found a later career committing petty crimes and insurance scams. Apparently, Smith had been a police informant and tried to blackmail the wrong guys. When he ended up in dozens of pieces in a chest at the bottom of the sea, the murderer hung onto his arm, because it had a rare tattoo and would serve as proof that he'd actually done the deed.
