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, fixem, 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 really 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!
