A mechanic was removing a cylinder head from the motor of a dodge SRT-4 when he spotted a well known cardiologist was there waiting for the service manager to come take a look at his car 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 SRT. The mechanic straightened up, wiped his hands on a rag and asked,"So Doc, look at this engine. I open it's heart, take the valves out, repair any damage, then put back in and, when I finish it works just like new,so how is it I make only $39000 a year, a pretty small salary, and you get the really big bucks, $1.6 million, when you and I do basically the same work"
The cardiologist paused, smiled and leaned over, then whispered to the mechanic..."try doing it with the engine running"
