"A mechanic was removing a cylinder-head from the motor of a Harley motorcycle when he spotted a well-known cardiologist in his shop. The cardiologist was there waiting for the service manager to come and take a look at his bike when the mechanic shouted across the garage: "Hey Doc, want to take a look at this?" The cardiologist, a bit surprised, walked over to where the mechanic was working on the motorcycle. The mechanic straightened up, wiped his hands on a rag and asked, "So Doc, look at this engine. I open its heart, take the valves out, repair any damage, and then put them back in, and when I finish, it works just like new. So how come I make $39,675 a year and you get the really big bucks ($1,695,759) when you and I are doing basically the same work?" The cardiologist paused, smiled and leaned over, then whispered to the mechanic... "Try doing it with the engine running.""
