An auto mechanic received a repair order that read: "Check for clunking sound when going around corners."

Taking the car out for a test drive, he made a right turn, and a moment later he heard a 'clunk.' He then made a left turn and again heard a 'clunk.'

Back at the shop he opened the car's trunk, and soon discovered the problem. Promptly he returned the repair order to the service manager with the notation, "Removed bowling ball from trunk".
