Motor cycle mechanic and heart surgeon

A motor cycle 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 and

... take a look at his bike.



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

question?"



The surgeon walked over to the mechanic. 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, and whispered to the

mechanic...



Try it with the engine running.
