A large crowd on the beach watched in horror a small boat just off shore that had taken a leak! Obviously, it was sinking slowly. The problem was--surrounded by sharks, hungrily circling. No lifeguards would venture out. So in the boat the teacher stood up, nervously eyeing the leak, and said, "Oh, well, here I go" and jumped over the side. Gobbled immediately. Meanwhile, the lawyer lit a cigarette, yawning. So the Preacher stood up, raised his eyes to Heaven, clasped his hands in front of his chest, and said, "Here I go, Lord. It's my turn." Gobbled immediately. At this point the lawyer laid his steely blue gaze on the far off beach, thinking about his Cadillacs and his private jet, and stubbed out his cig. Stood up. Over the side on to the back of first one shark, then another, then another, all the way to the shore! The crowd shrieked and screamed at him, "How did you do it?" He smiled. "Professional courtesy," he said.
