The Mechanic & the Cardiologist

 A Lexus mechanic was removing a cylinder head from the motor of a LS460 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 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.

The mechanic straightened up, wiped his hands on a rag and asked,  "So Doc, look
at this engine. I opened it's heart, took the valves out, repaired or replaced
anything damaged, and then put everything back in, and when I finished, it
worked just like new.

So how is it that I make $48,000 a year and you make $1.7M when you and I are
doing basically the same work?

The cardiologist paused, leaned over, and then whispered to the mechanic.......

"Try doing it with the engine running."
