A mechanic was removing the cylinder heads from the motor of a car
when he spotted the famous heart surgeon in his shop,
who was standing off to the side,waiting for the service manager to come to take a look at his car.

The mechanic shouted across the garage,

"Hello Doctor!!Please come over here for a minute."

The famous surgeon, a bit surprised, walked over to the mechanic.

The mechanic straightened up, wiped his hands on a rag and asked argumentatively,

"So doctor, look at this. I also open hearts, take valves out, grind 'em, put in new parts,
and when I finish this will work as a new one.
So how come you get the big money,
when you and me is doing basically the same work? "



The doctor leaned over and whispered to the mechanic.... .
