Geese Gone Violently Wild

Not only do I hate geese because they crap all around lakes and rivers, chase fish out of the shallows, and scare you to death in the spring when you mistakenly get too close to a nest, I hate them because they're cunning. Take the geese in the video below, for example. First they're all friendly, checking you out, looking for a bread scrap perhaps. Next thing you know, they go for your throat. Watch what happens to the angler in the clip. I give him credit for not swearing more extremely or sticking a treble hook in the neck of that sly, honking SOB. Anyone out there have a good goose story?
