A lawyer, an accountant, and an architect were on a cruise when the boat capsized. they rode a timber to a small desolate island.

"Somebody needs to swim ashore to get help," the accountant said.

"I'll do it," the lawyer said, and swam off into the shark infested waters. The sharks all parted ways, and one of them gave the lawyer a ride to shore.

"How's he doing that," the architect muttered. "

Professional courtesy," the accountant replies.
