My club used to put up a £10 special for the best 'bad trap' story and this was awarded to someone at the end of the year. One year it was won by someone saying that a pair of Mallards decided to build a nest on top of his shed, said everytime a pigeon tried to drop a Mallard would chase after it. Photographic evidence of the Mallards in question was produced to support his claim, the panel decided he would win the £10 that year even though the Mallards in the photo were most definitely plastic.
