A motorcycle mechanic was removing a cylinder head from the motor of a BMW M3 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 on the motorcycle.
The mechanic straightened up, wiped his hands on a rag and asked, "So Doc, look at this engine.
I opened its 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 £24,000 a year and you make £1.7million when you and I are basically doing the same work?"
The cardiologist paused, leaned over and then whispered to the mechanic;
"Try doing it with the engine running”.
