A mechanic was removing a cylinder head from the motor of a Dodge SRT-4 when he spotted a well-known cardiologist in his shop, who was waiting for the service manager to take a look at his car. 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 SRT. 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, a pretty small salary, 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.'
