My dad, 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 this notation:

"Remove bowling ball from trunk".
