This one is called –
The Doctor and the Mechanic.
A mechanic was removing a cylinder head from the motor of a Lamborghini, when he spotted a well-known heart surgeon in his shop…
The surgeon was waiting for the service manager to take a look at his car, 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 car.
The mechanic straightened up, wiped his hands on a rag, and said, “So, Doc, look at this engine… “
“I open its heart, take valves out, fix them, 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 thing?”
The surgeon paused, smiled, leaned over, then whispered to the mechanic…
“Try doing it with the engine running.”
