A mechanic was removing a cylinder head from the motor of a Harley motorcycle when he spotted a well-known heart surgeon in his shop.
The surgeon was there, waiting for the service manager to come and take a look at his bike.
The mechanic shouted across the garage, "Hey, Doc, can I ask you a question?"
The surgeon a bit surprised, walked over to the mechanic 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, fix 'em, put 'em 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."

Robert Parker Parrott

Born 5 Oct 1804; died 24 Dec 1877 at age 73.U.S. inventor who developed the rifled cannon known as the Parrott gun, the most formidable cannon of its time. He graduated from West Point Military Academy (1824), and spent 12 years with the Army, gaining ordinance experience. He was the army's inspector of ordinance at the private firm, West Point Foundry at Cold Spring when he retired from the army to become its civilian superintendent (31 Oct 1836) for 41 years. He perfected and manufactured a 10 pounder rifled cannon. It used a projectile with an encircling brass ring that expanded upon firing to fit the rifling grooves of the barrel. He patented both in 1861. Production of 20- and 30-pounder designs followed. During the Civil War years, he developed the Parrott sight and fuze.
