A Marvellous Answer

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.

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