When I was stationed in Kodiak, I attended the Ducks Unlimited banquet. At the banquet they had a duck calling contest. It was taken seriously and the winner garnered serious cred. The contestants were shielded from the audience and judge. This will not likely come as a surprise to anyone, but I am not very good at duck calling, among the many, many things I am bad at. When my turn came, I hammered that predator (rabbit squeal) call for all that it was worth. At first there was an uneasy quiet in the audience, then when they realized what was going on, they erupted in laughter.
