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"
