Ship Engine Failure.

A ship engine failed, NO ONE could fix it. Then they brought in a man with 40 yrs. on the job. He inspected the engine carefully. Then reached into his bag & pulled out a small hammer. He gently tapped a spot. Immediately, the engine rocked into life. It was fixed! 7 Days later, the owners got his bill for $10,000. 'What?!' the owners exclaimed. 'He scarcely did anything.' They asked for an itemized bill. His response: ”Tapping with a hammer = $2 Knowing where to tap = $9,998" Lesson: Don't Ever Underestimate Experience!
