Why sharks swim around you first ...

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 shit
inside!"
