Quoting Speedking1:

A mechanic was removing a cylinder head from the motor of a Harley motorcycle when he spotted a well known heart surgeon in his shop. The surgeon was there waiting for the service manager to come take a look at his bike when the mechanic shouted accross the garage, " Hey Doc , can I ask you a question ?
The surgeon , a bit surprised , walked over to where the mechanic was working on a motorcycle. The mechanic straightened up, wiped his hands on a rag and asked , " So Doc , look at this engine , I open it's heart , take valves out , repair any damage , then put them back in , and when I finish , it works just like new . So how come I get such a small salary and you get the really big bucks , when you and I are doing basically the same work ? "
The surgeon paused , smiled , leaned over , and whispered to the mechanic : " Try doing it with the engine running "
