A mechanic was removing a cylinder head from the motor of a Harley, when he
spotted the local heart surgeon in his shop. The surgeon was 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 professional
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 can open the heart of this engine, take
valves out, fix 'em, put in new parts; and, when I finish, this will work just
like a new one. So how come I get paid a pittance and you get the really big
bucks when you and I are doing basically the same work?"
The surgeon paused, smiled, leaned over, and whispered to the mechanic......
"Try doing it with the engine running."
