Doctor jokes-Duck analysis

Three doctors are in a steep blind as well as a bird flies overhead. The general practitioner looks during it as well as says, "Looks similar to a duck, flies similar to a duck... it's probably a duck," shoots during it though misses as well as a bird flies away.

The next bird flies overhead, as well as a pathologist looks during it, then looks through a pages of a bird manual, as well as says, "Hmmmm...green wings, yellow bill, quacking sound...might be a duck." He raises his gun to fire it, though a bird is long gone.

A third bird flies over. The surgeon raises his gun as well as shoots almost but looking, brings a bird down, as well as turns to a pathologist as well as says, "Go see if which was a duck."
