Lard From Live Pigs (1921)
The
Berliner Illustrirte Zeitung reported that a German farmer had developed a method of obtaining lard from live pigs by operating on the pigs to remove the rashers, then bandaging the pigs up and letting them heal. Supposedly the operation could be repeated three times a year. The story was subsequently widely reprinted by American and British papers which didn't realize it was a joke.
