The Mechanic and the Cardiologist

[Mark Feit]

A mechanic was removing a cylinder-head from the motor of a Honda
motorcycle 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 bike 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 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 make
$39,675 a year and you get the really big bucks when you and I are
doing basically the same work?"

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

"Try doing it with the engine running."
