Tony Signorini

In 1948, people believed that a species of 15-feet tall penguins existed in Florida after 15-inch penguin footprints were found on Gulf beaches. Zoologist Ivan Sanderson invested and even claimed it to not be a hoax. It turned out that Tony Signorini was stomping around in the sand wearing 30-pound, 3-toed lead shoes as a prank for over 10 years.
