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 take a look at his bike. As he waited, 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. Look at what I'm doing here. I open its heart, take the valves out, repair any damage, and then put them back in. And when I'm finished, it works just like new.
"So, Doc . . .how come I make only $39,600 a year. . .and you get the really big bucks. . .say $1,695,759 or so?? How come you make so much more when you and I are doing basically the same work?"
The cardiologist paused, smiled a minute and then leaned over. . .whispering into the mechanic's ear . . . .
"Try doing it with the engine running."
