Why Sharks Circle You Before Attacking.

Two great white sharks swimming in the ocean spied survivors of a
sunken ship. "Follow me son," the father shark said to the son shark and
they swam to the mass of people. "First we swim around them a few times with
just the tip of our fins showing." And they did. "Well done, son! Now we
swim around them a few times with all of our fins showing." And they did.
"Now we eat everybody." And they did.
        When they were both gorged, the son asked, “Dad, why didn't we just
eat them all at first? Why did we swim around and around them?"
        His wise father replied, "Because they taste better without the crap
