Thought provoking stuff

You may have already read this.. but still... this is quite thought provoking enough to repeat... A mechanic was removing a cylinder head from the motor of a Harley, when he spotted a world-famous heart surgeon in his shop. The heart surgeon was waiting for the service manager to come take a look at his bike. The mechanic shouted across the garage, 'Hey Doc can I ask you a question?' The famous surgeon, a bit surprised, walked over to the mechanic working on the motorcycle. The mechanic straightened up, wiped his hands on a rag and asked, 'So Doc, look at this engine. I also can open hearts, take valves out, fix'em, put in new parts and when I finish this will work just like a new one. So how come I get a pittance and you get the real big money, when you and I are doing basically the same work?' The surgeon paused, smiled and leaned over, and whispered to the mechanic..... 'Try doing it with the engine running'. Good one, ain't it... I thought a little more starting from this... will say more about that tomorrow... I'm beside myself today...
