When an outcome of a competition is determined by an unexpected crustacean which ultimately shifts the advantage to the victor over a seemingly more qualified competitor.
A man was in a fishing tournament where the winning fish was determined by weight. Upon initial examination the winning fish seemed comparable in length but was inexplicably thicker. After dissection lobsters were found in its stomach, which was the difference between winning and losing. He was a "Jolly Lobster."
