The Body of Nessie Found (1972)
Newspapers around the world announced that the dead body of the Loch Ness Monster had been found. A team of zoologists from Yorkshire's Flamingo Park Zoo, who were at Loch Ness searching for proof of Nessie's existence, had discovered the carcass floating in the water the day before. Initial reports claimed it weighed a ton and a half and was 15½ feet long. The zoologists placed the body in their van and began transporting it back to the zoo, but the local police chased them down and stopped them, citing a 1933 act of Parliament prohibiting the removal of "unidentified creatures" from Loch Ness.
The police took the body to Dunfermline for examination, where scientists soon threw cold water on the theory that the creature was the Loch Ness Monster. It turned out to be a bull elephant seal from the South Atlantic. The next day, the Flamingo Park's education officer, John Shields, confessed he had been responsible for placing the body in the Loch. The seal had died the week before at Dudley Zoo. He had shaved off its whiskers, padded its cheeks with stones, and kept it frozen for a week, before dumping it in the Loch. Then he phoned in a tip to make sure his colleagues found it. He had meant to play an April Fool's prank on his colleagues, but admitted the joke got out of hand when the police chased down their van. The seal's body was displayed at the Flamingo Park Zoo for a few days before being properly disposed of.
