A mechanic was removing a cylinder head from the motor of a Harley

Motorcycle when he spotted a well known heart surgeon in his shop.

The surgeon was there waiting for the service manager to come take a

look at his bike, when the mechanic shouted across the garage,

"Hey Doc, can I ask you a question...."

The surgeon, 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 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 get such a small salary and you get the really

big bucks, when you and I are doing basically the same work?"

The surgeon paused, smiled and leaned over, and whispered to the

mechanic... "Try doing it with the engine running."
