A psychiatrist, internist, surgeon, and pathologist go on a duck hunting trip. While waiting near the pond, a flock of birds files off and they all shoot. They hit one, but aren't sure what kind of bird it is because it looks different than the types of ducks native to that area.
The psychiatrist says, "Well, based on how that flock was swimming together and and their flight pattern when they flew off, that is classic behavior for ducks!"
The internist says, "Let's sample some feathers and run a bunch of blood tests. Then we'll know if it's a duck!"
The surgeon looks confused, hands the dead bird to the pathologist and asks, "Is this a duck?"
