A lawyer falls overboard while on a cruise. It happens to be shark infested waters and no one on the ship thinks he has a chance of surviving.

Everyone is astonished when the sharks form a column of twos and escort the lawyer back to the ship where he is pulled aboard.

The Captain of the ship says: " That is the most astonishing thing I have ever seen!"

The lawyer says: " Not really. Just orofessional courtesy".
