Morris was removing some engine valves from a car on the lift
when he spotted the famous heart surgeon Dr. Michael DeBakey, who
was standing off to the side, waiting for the service manager.

Morris, somewhat of a loud mouth, shouted across the garage, "Hey
DeBakey! Is that you? Come over here a minute."

The famous surgeon, a bit surprised, walked over to where Morris
was working on a car. Morris in a loud voice, where all could
hear, said argumentatively, "So Mr. Fancy Doctor, look at this
work. I also take valves out, grind 'em, put in new parts, and
when I finish this baby will purr like a kitten. So how come you
get the big bucks, when you and me are doing basically the same
work?"

Time practically stood still as the garage became quiet waiting
for the good doctor's reply. DeBakey was somewhat embarrassed
and in a clear distinct calm voice, said to Morris, "Try doing
your work with the engine running." And turned and walked away.
