British Waterways released a study claiming that a study conducted by Dr. Olaf Priol had found that ducks who lived on canals weighed, on average, a pound more than ducks who lived on rivers. The slow-moving canal water apparently provided the ducks with less opportunity for exercise, and so they gained weight. The study had an embargo date of April 1st (meaning that the media was not supposed to make it public until then), but the BBC, believing the study to be real, broke the embargo and discussed it earlier.
