The Mechanic

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.

The mechanic shouted across the garage, "Hey Doc can I ask you a
question?"

The surgeon, a bit surprised, walked over to the mechanic 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 valves out,
fix'em, put 'em 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, whispering to the
mechanic....."Try doing it with the engine running!"
