Did you hear about the lawyer on vacation whose sailboat capsized in dangerous, shark-infested waters? He surprised his traveling companions by volunteering to swim to the far-off shore for help. As he swam, his companions were startled by the appearance of two dorsal fins -- great white sharks, heading straight toward the lawyer. To their surprise, the sharks allowed the lawyer to take hold of their fins, and escorted him safely to shore.
When the lawyer returned with help, his companions asked him how he had managed such an incredible feat. The lawyer answered, "Professional courtesy."
