........................A plumber was called to a doctors home to fix leaking faucet that had kept the surgeon awake late at night. After a two-minute job the plumber demanded $150. The surgeon exclaimed, 'I don't charge this amount even though I am a surgeon." The plumber replied, "I agree, you are right. I too, didn't either, when I was a surgeon. That's why I switched to plumbing!"
