On the other hand, if you are out driving and there's a flock of Canadian Geese walking across the road, try only slowing down to 5 to 10 mph. They are used to people stopping until they finish crossing so they freak out when you don't.
Note: I generally do not advocate purposely messing with animals, but geese are evil! Also don't do this if there are young that might not be able to get out of the way in time.
